Capillary electrophoresis inductively coupled plasma mass spectrometry

摘要

Chemical speciation(extraction of elemental information and identification of molecular environment for an analyte in a complex sample) has been a ong sought after goal for analytical chemists.Recently,because of successful developments in more sensitive element-specific detectiors and gentle separation schemes,which preserve the true chemical information in a real sample,routine speciation experiments are becoing a common occurrence in the scientific literature.For many reasons,the combination of capillary electrophoresis(for separation of different chemical species) with inductively coupled plasma mass spectrometry (for element and isotope specific detection) has inductively coupled plasma mass spectrometry are discussed.Design consideration for instrument interface,anticipated difficulties with speciation experiments and applications for specific matrices and analytes are also presented in this article.
