‘Weighing’ atoms

Mass spectrometry is an accurate instrumental technique used to determine the relative isotopic mass (mass of each individual isotope relative to carbon-12) and the relative abundance for each isotope. From this, the relative atomic mass of the element can be calculated.

Some uses of mass spectrometry include:

carbon-14 dating

detecting illegal drugs

forensic science

space exploration.
