In-situ Differential Electrochemical Mass Spectrometry (DEMS) for Battery Energy Storage Devices

Introduction

The Differential Electrochemical Mass Spectrometry System is a state-of-the-art in-situ DEMS platform designed for advanced battery research and gas analysis. Engineered with a modular architecture and ultra-high sensitivity, this system enables real-time monitoring of gas generation and consumption during electrochemical reactions. It is especially well suited for studying lithium-ion, sodium-ion, metal-air, and Li-O2 battery systems, helping researchers gain deeper insight into electrode reactions, electrolyte decomposition, and battery failure mechanisms. The brochure presents the QAS100 Li as a turnkey DEMS solution for battery energy storage devices, with coupled electrochemical and mass spectrometry software for efficient testing and data processing.

Field-axis technology

One of the most important factors in the performance of a mass spectrometer is the transmission of the ions from the ion source into the mass filter. With the aid of field-axis technology, the ions are able to cross the peripheral fields of the separating system without any noteworthy interaction. This enables a high level of sensitivity (A/hPa) to be achieved without the need for pre and post filters.
