1 IMAGER introduction
1.1 IMAGER description
The β IMAGER originates from a technology initially developed for particle physics, and
adapted to Beta labeling detection in biology by BIOSPACE and Nobel Prize winner Georges CHARPAK.
It is primarily composed of a parallel-plate avalanche chamber (P.P.A.C.) -in essence the
particle detector-, and of an acquisition system based on an intensified CCD camera with
special optics. The chamber has an acquisition area of 200x250 mm². The zoom option allows an
acquisition to be made of the whole area or of a particular region of interest of the sample
(by automated camera repositioning), with improved spatial resolution.
A gas mix composed of argon (from an external bottle) and Triethylamine (TEA for short; from a tank inside the equipment) is fed into the chamber. The proportions of this gas mix
are computer-controlled; the computer also uses an array of sensors to monitor in real
time the status of the equipment. This gas mix then has to be safely exhausted after it has
been used.
The acquisition computer on which the β ACQUISITION program is installed controls the
entire system. This computer also hosts a modem used for remote assistance and diagnosis (Telemaintenance) by BIOSPACE. Data is usually analyzed on a networked
computer using the β VISION VISION VISION VISION+ + + + program.
The following two pictures highlight some β IMAGER elements and the usual on-site
β IMAGER configuration.

1.2 IMAGER operating principles
Samples are placed in a sample holder, which is automatically positioned inside the
detection chamber. The detector is sensitive to all β emissions, including tritium, as well
as all electron emitters such as 125I, 99mTc… all this with high efficiency.
Any β particle entering the detector’s area ionizes the gas. An electrical field created by
high voltages being applied onto the chamber grids accelerates primary ionization
electrons thus freed. Successive electron collisions in the gas result in an avalanche of electrons and a scintillation light. The intensified CCD camera then records every light
spot generated this way by every sample-emitted particle into the chamber.
After the video signal from the camera has been digitized, a reconstruction algorithm
allows the emission point to be calculated. Spatial co-ordinates from every particle are
then stored this way. Counting of every detected particle gives, when accumulated, a real-
time spatial distribution image of the sample activity.
The β IMAGER allows both accurate spatial localization of radio labeled sites and direct
quantification.

2 Sample handling
2.1 Introduction
The β IMAGER can handle several different types of sample holders designed for different types of samples:
• Slides holding cassette: for thin anatomical slices on glass slides – standard cassette for 15 standard microscope slides (25x75 mm2 to 26x76 mm2).
• Tritium sample holding cassette: for tritium-labeled samples: membrane, TLC plate, Whole Body Sections.
• C14 sample holding cassette: for C14 -or any other medium to high-energy isotope- labeled samples on thin and flexible substrate: membrane, Whole Body
Sections.
2.2 Glass slides cassette
This cassette is designed to hold 15 microscope slides with the following dimensions: 25x75 mm2 to 26x76 mm2, 1 mm thick. For other types of slides custom-built cassettes are
used in the same way, only the number of slides held in the cassette might change.
All sample holders come with a protective case. It must be kept clean (storage, periodical
wipe with alcohol). A glass sample preparation plate of size 35x30 cm2 comes with this cassette. Thus the
cassette can be manipulated on a flat & clean surface (periodically clean the plate with
alcohol) before or after an acquisition.
Handling principles:Handling principles:Handling principles:Handling principles:
• Place the sample holder on the preparation plate (cavities underneath).
• Unlock the lid and remove it.
• Cover the backside of the slides with copper tape. Do not leave any copper tape on the edges of the slides or on the side of the sample.
• Place all 15 slides in the cavities. All cavities need to be filled, by sample-free slides (with copper tape on one side) if necessary. The sample side must be
against the preparation plate, the copper tape side being at the top.
• Place the lid (springs underneath) on the sample holder, press the center of the lid and move all four knobs into the locked position.
• Take the sample holder by the grooves in the locking knobs or by the holes in the lid depending on the version, and turn it around to check the absence of dust and to check the absence of dust and to check the absence of dust and to check the absence of dust and rough edges on the sample side.rough edges on the sample side.rough edges on the sample side.rough edges on the sample side.

• Remove the cassette + protective plate assembly from the storage case.
• Place this assembly with the cassette upside on a table.
• Open the cassette by lifting the pressing plate once all four locking pins are
unlocked.
• A thin protective Mylar sheet should already be inside to protect the cassette’s
own Mylar window – if it is clean you may use it, otherwise replace it by a new sheet leaving some extra material on the sides – the whole window surface
must be covered by the protective Mylar sheet.
• Place the samples on this protective Mylar sheet, so that they are flat, that they are not superimposed and that the side to be analyzed is looking downwards
(against the protective Mylar sheet).
• Fold back the Mylar onto the samples.
• Place the pressing plate in its position (smooth side underneath) and press
lightly in its center to move the locking pins into the right position.

3 Acquisition Program: Presentation
3.1 Introduction
This new software is designed to work with Windows 2000.
Unlike its predecessor, it is fully integrated in Windows and benefits from it.
Familiarity with this program is not enough to run the β IMAGER; it is essential to be familiar also with sample handling for this instrument, since it is a critical part to get the
best images from the β IMAGER.
The β ACQUISITION software can operate in two different modes:
• Single Mode : you configure and run one acquisition after the other
• Sequence Mode: you configure a sequence of acquisitions and start the sequence that will automatically run the programmed acquisitions one after the
other. This can be very useful for zooming on different slides after a full field
acquisition for example.
The next sections explain how to use the β IMAGER with these two operating modes.

3.2.3 View Menu This menu is shown below:
The Overview Panel provides information on the current state of the instrument for service
purposes and, when an acquisition is running, the “Quality” criterion provides information
on how well the acquisition is running.
The “Quality” criterion is getting close to zero when the acquisition regulation is stable, i.e. the lower this criterion, the better the acquisition.
We recommend discarding acquisitions with a “Quality” criterion higher than 0.5 as the acquisitions would not have been stable enough.
This criterion is available in the properties of the image when the acquisition is opened
using the analysis program.
3.2.4 Help Menu This menu allows the user to display the version of β−ACQUISITION is currently installed by clicking on About.

3.4.3 Camera Window This window allows visualizing the events the way the camera detects them: as
disintegrations.
This window may be resized by dragging its edge while holding the mouse left button down.
It can be used:
� To check the activity or activity distribution of the sample � To detect non-radioactive hotspots: almost always present emitting points that
bias the amplification regulation (because they are not coming from
radioactivity). These usually come from fibers, hair, or large dust specks on the
sample. They also often create sparks (violent discharges in the detector).
Right click in the window area to modify the display palette (color scheme).
There are five available palettes:
� Gray: linear palette, from black to white � Invertgray: linear palette, from white to black
� BlackWhite: binary palette, either black (nothing) or white
� Gamma: logarithmic palette, from black to white (brings out low levels thus used
for low levels) � Rainbow: linear palette, from black to red (colored)
� Camera: linear palette, from black to red (colored) – same as before but
simplified
To detect non-radioactive hotspots, the best palettes are BlackWhite and Camera.
Note: The Camera window display is very demanding in computer resources. For this reason, please avoid enlarging the image too much & leaving it so.
3.4.4 Acquisition Window This window displays the accumulation of every acquired event since the beginning of the acquisition. In effect, this can be seen as what the autoradiographic image will look like.
This window may be resized by dragging its edge while holding the mouse left button
down.
Right click in the window area to modify the display palette (color scheme).

Right click in the window area to modify the display scale (scale range).
It can be left as automatic (checkbox checked) or the maximum & minimum be manually
adjusted by either using the sliding bars or by replacing the values in the corresponding boxes and pressing the enter key.
Note: The window display is very much simplified since such an item is very demanding in
resources. For this reason the image will have a much better resolution in the analysis
software but can also have a "cloud of points" effect if there are not enough statistics
3.4.5 Zoom Window If your β IMAGER has the zoom option, you have the possibility to physically zoom in a
particular region of the acquisition area.
Four zoom positions are available, and can be selected from the Control Window:
� Full field (200x250 mm2 or 15 slides)
� 6 Slides (120x160 mm2)
� 2 Slides (75x100 mm2) � 1/2 Slides (25x32 mm2)
| BI-R2-DAS-Manuel utilisateur BI-B

When the zoom is not in full field, a rectangle representing the area to acquire appears in the Zoom Window. This rectangle can be positioned precisely by holding the left mouse button while over the rectangle & moving the mouse to the required position.
This window may be resized by dragging its edge while holding the mouse left button
down.
It is also possible to change the background image of this window by pressing "Load" in the Control Window and selecting the full field image to be used in the appearing dialog
box.
Right click in the window area to modify the display palette (color scheme).
There are five available palettes:
� Gray: linear palette, from black to white � Invertgray: linear palette, from white to black
� BlackWhite: binary palette, either black (nothing) or white

Note: No changes are applied to the zoom configuration until you press "Change Change Change Change ConfigurationConfigurationConfigurationConfiguration" in the Control Window. This can be done just before starting the acquisition Note: DO wait that the zoom has finished moving before starting an acquisition.
4 Acquisition Program: Operation
4.1 Logging in
When the acquisition program is started, the user will be asked to identify before being
allowed to go any further.
Every user has to be registered by the administrator of the instrument using the Account Manager tool, accessible via the Tool menu by the administrator. When a different user starts using the instrument while the acquisition program is
running, the current user can log off via the File / log off menu.
The logging window is shown below:
When the Cancel button is clicked, the acquisition program terminates.
If the user is logging in for the first time, or if the password expired (c.f. the Administration
section), the user is asked to enter a different password.
Note: The Login & Password are case-sensitive.
There are 3 access levels available:
• UserUserUserUser: to start, stop configure an acquisition & a sequence.
• Advanced UserAdvanced UserAdvanced UserAdvanced User: to refill the TEA and do all of the above.
• AAAAdministratordministratordministratordministrator: To manage users, correction files export log files and do all of the above.
| BI-R2-DAS-Manuel utilisateur BI-B
- 30 -
4.2 Loading / Unloading the Drawer
When the acquisition program is started or when an acquisition is stopped, a detector
purge is launched if it was not done or completed before.
Also, the zoom is indexed every time the program is launched.
If the detector is purged, its pressurization is initiated, and the status box in the Control
Window displays "Pressurizing detector".
Once the detector has reached the required pressure, the instrument goes into a waiting
state (Ready for opening or starting an acquisition in the status box).
At this point the drawer can be opened by pressing the Open loader button at the front of the instrument.
It can then be loaded or unloaded as required.
Note :If the instrument has not been used for a long time, hold the drawer closed with your hand until it goes into alarm (red LED at the front of the instrument) to allow the loader support plate to fall in place: the seal of the detector might retain the plate longer than expected if it was not exercised for a period of time! If this happens the drawer may be blocked and the seal may be ripped! The drawer alarm can be cleared by pressing the Clear Drawer Alarm button at the front of the instrument. Once loaded, the drawer can be closed by pressing the Close loader button at the front of
the instrument.
Note: Do not hesitate to hold the drawer if the cassette is not positioned properly in its groove! The detector may be damaged and the drawer may be blocked if you fail to do so! The drawer alarm can be cleared by pressing the Clear Drawer Alarm button at the front of the instrument.
4.3 Acquisition Configuration
Before an acquisition is started, the correct acquisition parameters have to be entered by
the user. They are critical for a good acquisition since they are not just information, but
are used for the regulation of the acquisition.
In the Control Window:
� Choose the isotope (Isotope box)
| BI-R2-DAS-Manuel utilisateur BI-B
- 31 -
� Choose the cassette or sample holder (in Sample Holder, click on the required sample holder);
The available sample holders then appears in a menu: choose the correct one.
Note: The selected sample holder name will then be highlighted by a check symbol.
| BI-R2-DAS-Manuel utilisateur BI-B
- 32 -
� If required, change the Acquisition Mode, which is as a default the optimal
setting for the selected cassette : Low Resolution for 3H cassette (the only mode
compatible with this cassette) and High Resolution for the other cassettes.
Change this setting to Low Resolution if you experience sparks : this low-resolution mode is more tolerant to not-so-perfect samples (flatness, cleanliness)
but as its name indicates the resolution is poorer, especially with other isotopes
than Tritium.
� As an option, stop conditions can be entered either as a set time in hours &
minutes or as a required count. Once this is done, " Use stop conditions " must
be checked & the " Apply " button must be pressed to take these stop conditions
into account.
Notes : Stop conditions can be changed while the acquisition is running, by entering the new values followed by " Apply ". You can use both stop conditions in time and count at the same time, the first condition to be reached will stop the acquisition.
• If another acquisition will be run on the same sample (without removing it from the instrument), the detector purge & gas preparation can be skipped by
unchecking " Purge on Stop ".
• The name & path of the acquisition file to be acquired are automatically
generated. However, they can be changed in the " Acquisition Name " box.
• Comments can also be entered & will be recorded with the file. (Up to 256 characters).
At this point, the zoom can be configured or the acquisition started.
| BI-R2-DAS-Manuel utilisateur BI-B
- 33 -
4.4 Zoom Configuration
Before zooming in a part of the acquisition area, it is essential to run a full field
acquisition to ensure of the absence of non-radioactive hotspots (they can be detected
with the Camera Window), which are induced by the presence of fibers, hair, flaking samples, large dust specks.
Those non-radioactive hotspots -besides being non-desirable signals- can alter the
regulation of the acquisition if too important proportionally to the radioactive signal (not being radioactive, they have different characteristics from the expected signal with which
the regulation is made), and they can create sparks (violent electrical discharges in the
detector).
Those non-radioactive hotspots can be detected since they are almost always present in
the Camera Window, unlike radioactive signal.
The zoom configuration parameters can be changed in the " Zoom Mode " part of the
Control Window in conjunction with the Zoom Window ( icon).
Four zoom positions are available, and can be selected from the Control Window:
� Full field (200x250 mm2 or 15 slides)
� 6 Slides (120x160 mm2) � 2 Slides (75x100 mm2)
� 1/2 Slides (25x32 mm2)
Note: The default Zoom mode when the acquisition program is started is Full Field. Therefore an acquisition can be started without configuring the zoom if the zoom options did not change.
To ease the zoom positioning, a full field image of the sample to be acquired can be
loaded as a background image for the Zoom Window, by pressing " load file " in the Control Window.
When this done, the following dialog window appears:
| BI-R2-DAS-Manuel utilisateur BI-B
- 34 -
The required BVR file to be used as a background image can then be selected to appear in
the Zoom Window.
Right clicking anywhere in the Zoom Window allows you then to change the color palette
or the scale.
When the zoom is not in full field, a rectangle representing the area to acquire appears; This rectangle can be positioned precisely by holding the left mouse button down while over the rectangle & moving the mouse to the required position.
In Single Mode : In Single Mode : In Single Mode : In Single Mode :
Once the zoom is fully configured press "Change ConfigurationChange ConfigurationChange ConfigurationChange Configuration" button to validate it. The
zoom is then automatically positioned and you can start the acquisition (if you have
configured the other parameters for the acquisition)
In Sequence Mode : (see Sequence MoIn Sequence Mode : (see Sequence MoIn Sequence Mode : (see Sequence MoIn Sequence Mode : (see Sequence Mode section)de section)de section)de section)
The zoom is automatically positioned for each acquisition of the sequence – you don’t need to press "Change ConfigurationChange ConfigurationChange ConfigurationChange Configuration" button.
4.5 Acquisition Start / Stop
Before starting an acquisition, it has to be configured.
| BI-R2-DAS-Manuel utilisateur BI-B
- 35 -
Once the acquisition has been configured (including zoom configuration and its validation
with "Change Configuration" button), pressing "Start new" button in the Control Window
will start the acquisition.
As soon as an acquisition is in progress (including the gas preparation phase), the text of
the "Start new" button toggles to " STOP ". The acquisition can thus be stopped at any time (even before any event was acquired i.e.
during gas preparation). The acquisition can also stop automatically on Stop Conditions if selected and applied.
4.6 Gas Purge / Preparation
According to the phase the β IMAGER is in, the "Purge / Preparation " button in the Control Window will be available as "Purge" or as "Preparation".
If the gas mix in the detector contains TEA (gas preparation or ready for an acquisition), the available button is "Purge" and by pressing it the TEA will be cleared from the detector
to allow the drawer to be opened.
If the gas in the detector is only argon (or argon + air after drawer opening), the available button is "Preparation" and by pressing it the detector gas mix will be prepared for
acquisition; the acquisition parameters can be entered following this thus saving a few
minutes.
Once the gas preparation is launched, pressing "Start New" will start the acquisition as soon as the preparation is completed.
At any rate pressing "Start new" will launch a preparation for your first acquisition.
If the acquisition program was closed without having completed a detector purge, it will automatically do so when the program is restarted.
To avoid purging when the sample is not to be removed, the "Preparation" button can be used immediately.
| BI-R2-DAS-Manuel utilisateur BI-B
- 36 -
4.7 During the Acquisition
4.7.1 Details of the run During the acquisition you can read on the Control Panel : � Acquisition time (or Time Left by clicking on the value if stop conditions are used).
� Total count (or Remaining Count by clicking on the value if stop conditions are used).
� Count per minute ( 100 < cpm < 120000)
4.7.2 Saving part of the acquisition The data already acquired during an acquisition can be exported & analyzed as a new
acquisition file without having to interrupt the run, simply by clicking on the icon. A dialog window then appears indicating the progression of the save process.
The file created in this manner can immediately be moved & analyzed.
Once the acquisition has been stopped (even after a program restart) this functionality is
still available.
4.7.3 Windows Uses
The Camera Window ( ) allows the user to:
• Check the presence of non radioactive hotspots (points permanently present)
• See the activity distribution of the sample (s)
The Acquisition Window ( ) allows the user to see the events already acquired.
The Acquisition Control allows the user to see time and count information on the
acquisition, to check the instrument status, to modify the stop conditions and to interrupt
the acquisition.
| BI-R2-DAS-Manuel utilisateur BI-B
- 37 -
4.8 Sequence Mode
The β ACQUISITION software allows an acquisition to be pre-programmed and run as a
sequence (up to fifty consecutives acquisitions) to be configured and customized by the user. This can be of particularly useful to automatically acquire zoom images after a full
field acquisition.
The following sections describe the different functions that are specific to the sequence mode. Details regarding the main menu and the default dialog box (single mode) are still
relevant to sequence mode version. The Sequence mode is controlled in the same control
window as the usual Single Mode.
To use the Sequence Mode, first press the "Sequence Mode" button.

Important : Important : Important : Important :
Before running a sequence with zoom in a part of the acquisition area, it is
essential to run a full field acquisition to ensure of the absence of non-
radioactive hot spots (they can be detected with the Camera Window), which
are induced by the presence of fibers, hair, flaking samples, large dust specks. Those non-radioactive hotspots -besides being non-desirable signals- can alter the
regulation of the acquisition if too important proportionally to the radioactive signal (not
being radioactive, they have different characteristics from the expected signal with which
the regulation is made), and they can create sparks (violent electrical discharges in the
detector).
Those non-radioactive hotspots can be detected since they are almost always present in the Camera Window, unlike radioactive signal.
4.8.2 During a sequence : The number of the running acquisition can be seen in the "Current acquisition" box. As in
Single Mode the configuration and the time and counting information of the running
acquisition are set in the Acquisition Control window. The zoom selected area is set in the
Zoom window. The image is displayed in the Image window.
The “Stop” button can be pressed without having to wait for the stop conditions to be fulfilled. (for example, if you want to modify the acquisitions parameters).
From an interrupted sequence it is possible to run the next acquisition of the sequence by
pressing the "Run Next" button.
To modify acquisition settings : stop the running acquisition, select the number of the acquisition to be modified, modify it and press the "Add to sequence" button.
During the sequence you can modify the stop conditions of the running acquisition by
changing them and pressing the "Apply" button in the Stop Conditions zone as you would in Single Mode. To change the stop conditions of another acquisition in the sequence you have to stop the sequence, change the stop condition and restart the sequence as
explained before.
In the sequence mode, you cannot use the “Purge / Preparation” button, and you cannot launch the TEA Fill procedure. In order to do this, you will have to stop the sequence and
go back in the single acquisition mode, by pressing the "Single Mode" button. Once in single acquisition mode, you will be able to go back in the sequence mode.

4.8.3 Stopping a sequence
When the last acquisition in the sequence is over the sequence is automatically
stopped.
If you check the purge checkbox in the stop conditions of the last acquisition, a
purge automatically follows the acquisition. When the purge is over you can
then remove your sample as in Single acquisition Mode.
If you didn't set a purge in the stop conditions of the last acquisition the β
IMAGER is waiting for another acquisition. You can then :
� Reset the sequence, program a new sequence and run it on the same
samples
� You can also go back to Single Mode and start a new acquisition
When no automatic purge is programmed going back to Single Mode to purge
manually allows the removal of the samples.
Note : You can stop any acquisition of the sequence at any time with the Stop
button
Note : You cannot launch twice the same sequence.

When the administrator creates a new login account the following window appears:
A temporary password has to be assigned : the new user will be prompted to change the
password on first use before being allowed to go any further.
A comment is associated with this account creation.
When the administrator revokes a login account, a comment is associated with the
deletion (“Reason for revocation”: window appears on clicking the Revoke button).
Notes: When a different user starts using the instrument while the acquisition program is running, the current user can log off via the File / log off menu. If the user is logging in for the first time, or if the password expired, the user is asked to enter a different password before being allowed to go any further. The Login & Password are case-sensitive. The Password has to be alpha-numerical & of at least 8 characters.

5.2 Cassette Manager
In order to reduce unhomogeneity of the acquisition field of view (compulsory in some
acquisition modes), a correction is applied in real time to the acquisition data; this
correction is reversible & is specific for a sample holder (cassette) in its designed operating mode.
Generating & managing the homogeneity correction files is usually done by Biospace lab
or its Representative: what follows is informational & does not require maintenance by the instrument administrator.
There are 3 operating modes corresponding to a different type of sample holder:
• Tritium cassette
• Slides cassette
• High Energy membrane cassette (14C cassette)
A correction file has to be associated with each cassette (i.e. if you possess several
cassettes of the same type, you need to use as many different correction file); this is done
via the tool shown below, the Cassette Manager tool:
Declaring a correction file for a type of cassette makes it unavailable for the other cassette
types.
The cassette name declared in the Cassette Manager tool has to be identical to the correction file name (minus the extension *.mat), which is stored in the acquisition
program directory, subdirectory “Config”.
Those correction files are generated using purpose-made homogeneity standards with the help of a service tool called “BV Acquisition Tool”. (This tool is for service only and is not
intended for a Customer use).

5.3 Export Log File /Audit
A log of the instrument operation is kept and stores the following with current login &
access level, time, and date information:
• Acquisition start / stop (with details of the run: parameters, properties)
• TEA Tank fill
• Account creation / deletion / modification
• Cassette correction creation / deletion
• Errors
This log can be exported by the administrator as a text file using Export Log File in the Tools menu.

6 IMAGER: Maintenance
6.1 TEA tank fill
TEA tank fill is allowed when a set low level is reached. When the TEA level indicator goes from green to orange, a tank fill is possible.
When the TEA level indicator is red, an acquisition cannot be started since there is not enough TEA left in the tank.
For a TEA tank fill, you will need:
• TEA pump TEA pump TEA pump TEA pump (When refilling for the first time, check that the input tube of the pump -going into the bottle- has the right length to go till the bottom of the bottle)
• A new 1 liter TEA bottle A new 1 liter TEA bottle A new 1 liter TEA bottle A new 1 liter TEA bottle

� Connect the tube of the pump where the cap was.
� Uncap the TEA bottle and push the pump body onto the bottleneck until it is tight.
� Pump the TEA up from the bottle by squeezing the ball on top of the pump, and
regularly check the on-screen TEA level. The display is not refreshed instantly, so
allow for a few seconds’ delay.
Note : After priming, lifting the bottle will result in the liquid flowing on its own into the tank. However, this proves unsafe since the bottle may be dropped & break.
� When the bottle is empty, continue to pump to clear any TEA from the tube.
Note : The TEA level will never reach 100 %. Do not try to fill in more than 1 liter you might damage the β IMAGER.
� Remove the pump from the bottle (after checking there is no TEA left in the tube)
and screw the cap back on the side of the β IMAGER. Do the same for the
bottle’s cap.
� You can then press the "End of Fill" button to pressurize the detector again.
� Wash the pump under cold water, let it dry and store it until the next refill.
Alternatively, let the pump dry in a fume cabinet.

Note : In case the TEA is spilled (on the floor or inside the instrument), power off the β IMAGER, wipe & wash with water or diluted acid (only the floor, not inside the machine!). See the Material Safety Data Sheet (MSDS) for TEA.
If you do not feel comfortable with this filling procedure, do not hesitate to get in contact with our maintenance engineers to guide & assist you through a remote support link & telephone.
Note :Note :Note :Note : Warning, Triethylamine is an organic compound of class 3, subsidiary risk of class 8, referenced n° UN or UTA: 1296. We strongly advise to read the appended MSDS for TEA. European directives for environmental rejection limits regulate Triethylamine. In normal operation, the β IMAGER is in conformity and is well below the regulations published Feb. 2d, 1998 in relation to all-type emissions.

6.2 Argon cylinder replacement
The Argon used must be of C grade or better C grade or better C grade or better C grade or better (N56): Purity ≥ 99,998 %
(H2O ≤ 3 ppmV, O2 ≤ 3 ppmV, CnHn ≤ 3 ppmV, N2 ≤ 3 ppmV)
The β IMAGER operates with average gas flows between 700 cc/min during the preparation & purge phases and 100 cc/min during standby phase between 2 acquisitions
(150 to 300 cc/min during the acquisition phase).
Typically, the average autonomy of a B50 Argon cylinder is 1 to 3 months, depending on
the instrument’s use. When the Argon cylinder is almost empty, the acquisition software displays a warning
message (the detection is done using a pressure switch on the bottle’s regulator). It then
automatically stops the acquisition & purges the detector in order for the drawer to be
opened to remove the sample. The software prohibits acquisition until the bottle has been changed.
Argon cylinder replacement procedure
1. Close the cylinder to be replaced.
2. Wait until no bubbles are left in the bubbler, and that both regulator gauges on the bottle indicate 0 bar (you can create a leak to speed this up by slightly
undoing one of the nuts, on the tubing going to the instrument).
3. Remove the two-stage regulator from the bottle. Connect it on the full bottle.
4. Open the new bottle. The 1st stage regulator should indicate around 200 bars (≅
2850 psi), the 2nd stage regulator 4 bars (≅ 60 psi). 5. Start an acquisition following the standard steps.
RRRRecommendationsecommendationsecommendationsecommendations:
� It is advised to keep an extra Argon cylinder at hand to avoid delay in replacing the bottle when empty.
� The gas cylindersgas cylindersgas cylindersgas cylinders must be attached & securedattached & securedattached & securedattached & secured to a stable & permanent rack to
prevent them from falling.

6.4 Remote help link (Telemaintenance)
If you took this option, Biospace support engineers can connect to your instrument to
troubleshoot it directly from Paris. This has the advantage of speed (it can be done
immediately) and the advantage of efficiency: by looking directly at the instrument, the diagnostic from Biospace will gain in accuracy.
To activate the remote link:
� Connect the modem line from the computer to the correct telephone socket (it should be accessible from overseas directly & Biospace should have the
telephone number) if a phone connection is used.
� Start the remote link application by clicking on the PC Anywhere shortcut on the
desktop , & in the new application window select "Help from Help from Help from Help from Biospace (Modem)Biospace (Modem)Biospace (Modem)Biospace (Modem)" or "Help from Help from Help from Help from Biospace (Internet)Biospace (Internet)Biospace (Internet)Biospace (Internet)" depending on the type of connection available.
� After a few seconds, a panel appears with the message: "Waiting for connectionWaiting for connectionWaiting for connectionWaiting for connection" � Contact Biospace to confirm that the connection was enabled

The symptoms of lung oedema often do not become manifest
until a few hours have passed and
they are aggravated by physical effort. Rest and medical
observation are therefore essential. Immediate
administration of an appropriate spray, by a doctor or a person
authorized by him/her, should be
considered. The odour warning when the exposure limit value is
