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

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.
