单颗粒、单细胞 SP-ICP-MS分析技术

• PerkinElmer 公司极力倡导的单颗粒、单细胞ICP-MS(single particle-ICPMS)技术被公认为一种

定性和定量测定含有特定元素的低浓度的单颗粒最有前途的方法。

• 单颗粒目标可以是纳米粒子,也可以是PM2.5/PM10等大气粉尘颗粒物,或者合成的超细颗粒物

及包合物等,更可以是生命科学研究前沿的细胞,藻类,病毒等活体小颗粒型目标物。

• 相对传统的元素监测方法,SP-ICP-MS技术可快速有效并提供更多的信息:它能够测定颗粒尺寸

分布、颗粒个数,颗粒内部元素的浓度、颗粒外部溶解出来的元素浓度等。而且,它能够区分含

有不同元素的特定粒子。
