HPR-40 DEMS

Solutions for Dissolved Gas Analysis and Off-gas Analysis in Electrochemistry

The Hiden HPR-40 DSA Membrane Inlet Mass Spectrometer (MIMS) is a compact bench-top gas analysis system for real-time quantitative analysis and monitoring of dissolved/evolved gases.

The HPR-40 DSA is available with a range of DEMS cells for differential electrochemistry mass spectrometry. DEMS cells include a nano porous membrane interface for fast response in-situ determination of gaseous and volatile electrochemical reactants, reaction intermediates and products in real time.

OVERVIEW

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. Hiden Analytical offer a range of DEMS cells with electrolyte/nanoporous sampling interface to the Hiden HPR-40 DSA Mass Spectrometer

FEATURES

  • Analysis of dissolved species with mass range 200 amu (300 amu option)
  • Vitreous Carbon – User coatable working electrode
  • Replaceable nanoporous membrane
  • 4 Ports for additional electrodes
  • Interface to the Hiden HPR-40 DSA mass spectrometer

A novel differential electrochemical mass spectrometry (DEMS) cell for integration with the Hiden Analytical HPR-40 DSA membrane inlet mass spectrometer systems. The new cell, developed by Ezra L. Clark and Prof. Alexis T. Bell of The University of California, Berkeley Lab, coupled with Hiden’s differentially pumped mass spectrometer system provides for in-situ mass resolved determination of gaseous or volatile electrochemical reaction intermediates and products in real-time.
