An overview of electrochemistry combined with mass spectrometry

• Types of electrochemical cell.
• Electrochemistry on microchips for coupling to a mass spectrometer.
• Inner workings of a potentiostat.
• Ionization methods in mass spectrometry.
• Electrochemical reactions on biomolecules and xenobiotics.

This is an overview of historical and technical aspects of the combination of electrochemistry with mass spectrometry. Some of the applications are highlighted. For a complete overview, the reader is referred to the other contributions in this Special Issue of TrAC.
