毛细管电泳-电感耦合等离子体质谱联用技术及其元素形态分析的新进展

Recent Progress of Trace Element Speciation Analysis by Capillary Electrophoresis-Inductively Coupled Plasma Mass Spectrometry

元素的形态与它的毒性和生物活性密切相关。近年来,毛细管电泳与电感耦合等离子体质谱联用(CE-ICP-MS)技术成为元素形态分析的有力手段,得到了迅速发展。本工作阐述了CE-ICP-MS联用的各种接口方式,并讨论了几种接口及雾化器装置的优点和不足;综述了近几年采用CE-ICP-MS联用技术对痕量元素形态分析的新进展,对CE-ICP-MS联用技术在元素形态分析上的潜力、限制及发展趋势作了讨论。

The elemental speciation has a close relationship with its toxicity and biological activity. Recent years, capillary electrophoresis-inductively coupled plasma mass spectrometry （CE-ICP-MS） has developed quickly and become a powerful technique to analyze the element speciation. The interface issues about the CE combining with the ICP-MS were described. And then the merits and weaknesses of several interfaces and aerosol control units are discussed. The progress of element speciation analysis in environment by CE-ICP-MS hyphenated techniques was further expatiated. The potential limitations and trends of the CE-ICP-MS hyphenated techniques in elements speciation analysis were explained, and dissected in detail.
