Recent Developments in Electrochemistry-Mass Spectrometry

Hyphenation of electrochemistry and mass spectrometry is an attractive method to investigate oxidation and reduction processes. By using mass spectrometry, electrochemically generated products can be identified. In this Review, different approaches to electrochemistry-mass spectrometry will be summarized, including hyphenation of electrochemical flow cells to mass spectrometry as well as integration of separation steps between electrochemical reactions and detection of products. Fields of application range from bioanalytical studies to studies regarding corrosion, electrosynthesis and energy carriers. Important historical developments will be highlighted, followed by an overview of terminology and instrumental setups and discussion of developments within recent years (2017-2020).
