HPR-40 DEMS

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

  • Model: HPR-40 DEMS
  • Manufacturer: Hiden Analytical

The Hiden HPR-40 DEMS is a bench top or mobile cart mounted module for analysis of dissolved species in electrochemistry. The system is modular and adaptable. The system includes two differential electrochemical mass spectrometry ‘DEMS’ cell inlets, designed for material/ catalysis studies, cell type A, and electrochemical reaction studies, cell type B.

Applications

  • DEMS
  • CO2 Reduction
  • Electrolysis
  • Cathode Studies
  • Lithium Ion Battery Development
  • Fuel Cell Studies
  • Electrocatalyst Studies
Category:

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.

For applications where online electrochemical MS, OEMS, from an existing cell or reactor is required, a range of standard inlet options is available offering both evolved off-gas and dissolved species analysis solutions. Electrochemical cells that can be interfaced to the Hiden HPR-40 DEMS system include selected models from: Redoxme AB, and EL-Cell®

DEMS cell – A differentially pumped mass spectrometry inlet for in situ mass resolved determination of gaseous or volatile electrochemical reactants, reaction intermediates and products in real time.
