Abstract
Abstract
The characterization of the redox behavior of analytes is a very important aspect for many applications. Pure
electrochemical approaches can provide useful information on electroactive species, but are of limited use regarding the
identification of generated species. The hyphenation of electrochemistry and mass spectrometry (EC-MS) is a powerful
method to investigate redox systems. In the present work, we show a simple approach to on-line EC-MS based on the
application of electrochemical flow cells with implemented disposable electrodes. They are connected to electrospray
ionization mass spectrometry (ESI-MS) via fused silica capillary tubing. The modularity of the flow cells offers a high
flexibility of experimental setup and settings, so that a fast detection of oxidation or reduction products can be
achieved. The usage of disposable electrodes guarantees a high level of quality assurance for EC-MS measurements.
