Résumé
Electrochemical or photo-electrochemical reactions in both electrospray ionization and laser desorption ionization are discussed stressing the role of the electrode reaction in influencing the ionization process. In particular, upon application of a high voltage during electrospray ionization, the emitter includes a working electrode, where redox reactions are observed, such as electro-generation of benzoquinone and metal ions. In contrast, the target plate in laser-induced desorption ionization also acts as a photo-electrode, especially when modified with a mesoporous semiconductor. We illustrate here how these electrochemical reactions can be used for tagging purposes, and for oxidative or reductive dissociation reactions.
