In‑Situ Differential Electrochemical Mass Spectrometry (DEMS)

In‑situ differential electrochemical mass spectrometry (DEMS) is a detection technique that organically combines electrochemical methods with mass spectrometry analysis. It employs a hydrophobic, gas‑permeable membrane as the interface between the electrochemical reaction and mass spectrometric detection, and, together with a high‑efficiency vacuum system, dramatically shortens the time from product generation to detection, thereby enabling rapid, real‑time monitoring of reaction processes. The technique allows online analysis of volatile gas products, reaction kinetics, and intermediate characteristics during electrochemical reactions. In particular, when an electrode reaction generates multiple products, DEMS can simultaneously resolve the evolution of the Faradaic current of each product as a function of potential or time, intuitively revealing the reaction mechanism. In potential sweep experiments, the ion current signals corresponding to different species and the Faradaic current are collected concurrently, forming a mass spectrometric cyclic voltammogram (MSCV). The resulting data not only provide a qualitative judgment of the electrochemical reaction but also offer significant quantitative analytical value, making DEMS a powerful tool for studying complex electrochemical processes.
