Capillary Electrophoresis with Mass Spectrometry: Applications to Metabolomic Analysis

The use of capillary electrophoresis with mass spectrometry (CE-MS) for metabolomic analysis has substantially increased in recent years. This hyphenated technique takes full advantage of the high separation efficiency of CE and the identification capability of MS, providing a powerful tool for rapid analysis and identification of metabolites in complex biological samples. This article focuses on an overview of some recent applications of CE-MS in metabolomics studies. We also discuss the techniques for the coupling of CE with MS and the potential of 2-D CE-MS for metabolomic analysis.
