DEMS
for Differential Electrochemical Mass Spectrometry
Differential Electrochemical Mass Spectrometry (DEMS) is an analytical technique that combines electrochemical half-cell experimentation with mass spectrometry.

It allows in situ mass resolved determination of gaseous or volatile electrochemical reactants, reaction intermediates and products in real time.
The experimental setup consists of an electrochemical half-cell, the membrane interface and a vacuum system including a quadrupole mass spectrometer.
DEMS is closely related to membrane inlet mass spectrometry (MIMS).
