On-line electrochemistry – MS and related techniques

Abstract.

This review summarizes publications on the on-line coupling of electrochemistry with mass spectrometry. After a brief historic introduction it is divided into three parts, organized in order of increasing complexity of the experimental arrangement. The first section deals with the use of the electrospray ion source as an electrochemical reactor for oxidation or reduction reactions. It is followed by the second part which covers the hyphenation of different kinds of electrochemical flow cell with a variety of ionization interfaces. The last section focuses on the on-line coupling of chromatographic techniques with electrochemical flow cells and mass spectrometry.
