High rate detection of volatile products using differential electrochemical mass spectrometry: combining an electrode-coated membrane with hydrodynamic flow in a wall-tube configuration.

We present an experimental system that combines differential electrochemical mass spectrometry with hydrodynamic flow consisting of an impinging jet in a wall-tube configuration. This assembly allows simultaneous detection of electrochemical signals along with monitoring of dissolved gas species using differential electrochemical mass spectrometry under well-defined hydrodynamic conditions and ...

Mass spectrometric methods for monitoring redox processes in electrochemical cells

Electrochemistry (EC) is a mature scientific discipline aimed to study the movement of electrons in an oxidation-reduction reaction. EC covers techniques that use a measurement of potential, charge, or current to determine the concentration or the chemical reactivity of analytes. The electrical signal is directly converted into chemical information. For in-depth characterization of complex elec...

Liquid chromatography with post-column electrochemical treatment and mass spectrometric detection of non-polar compounds.

The first hyphenation of high performance liquid chromatography (HPLC), electrochemical online oxidation and mass spectrometry (MS) is described. Ferrocenecarboxylic acid esters of various alcohols and phenols have been synthesized, separated by reversed-phase HPLC and oxidized (ionized) coulometrically prior to single quadrupole MS analysis using electrospray ionization (ESI) and atmospheric p...

Online electrochemistry/mass spectrometry in drug metabolism studies: principles and applications.

IMPORTANCE OF THE FIELD Conventional metabolism studies in early stages of drug development include in vitro tests, often based on hepatic cells and cell extracts, as well as in vivo tests on the basis of animal models. Complementary to these existing techniques, the electrochemical study of oxidative metabolism reactions is gaining increasing attention. Electrochemistry (EC) allows the fast de...
