Product Description & Specifications

Model: MS-FC
 
The PM-DEMS, a new-generation all-in-one multifunctional in-situ differential electrochemical mass spectrometer, is designed for online qualitative and quantitative analysis of gaseous products, volatile intermediates and final products generated during electrochemical reactions.
In-situ Differential Electrochemical Mass Spectrometry (DEMS) is an advanced in-situ electrochemical testing technique developed by combining electrochemistry and mass spectrometry. It adopts a hydrophobic gas-permeable membrane as the interface between electrochemical reaction and mass spectrometry, paired with an advanced vacuum system to shorten signal acquisition time, enabling immediate detection right after electrochemical products form.
 
It can perform in-situ measurement of volatile gaseous products, kinetic parameters, intermediates and structural properties of electrochemical reactions. When multiple products co-evolve during electrode reactions, DEMS can simultaneously track the variation of Faradaic current of each product against electrode potential or time. During potential scanning, ion currents corresponding to specific substances are recorded synchronously with Faradaic electrode currents to generate mass spectrometric voltammograms (MSCV).

Product Features

  1. Integrated gas-liquid dual sampling channel for simultaneous detection; compatible with electrocatalysis, photocatalysis, thermocatalysis and battery gas evolution testing, eliminating the need for multiple instruments.
  2. Ultra-high sensitivity with precise real-time monitoring; test results match chemical reaction behaviors without signal lag.
  3. Millisecond-level response time and scanning speed to support rapid online analysis.
  4. Dual detectors (Faraday cup + electron multiplier) deliver ultra-wide detection range from 100% down to ppb level with outstanding sensitivity.
  5. Professional analytical software supporting multi-component sampling for qualitative and quantitative gas analysis.
  6. Temperature-controllable sampling pipelines to prevent condensation of sampled gas during transmission.
  7. Bakeable mass spectrometry chamber to effectively reduce background gas interference.
  8. Multi-channel input and output signals enable automatic control with external analytical instruments.
  9. Built-in filament pressure protection function to extend filament service life.
  10. Customizable sampling system to realize pre-treatment of inlet gas and multi-channel sampling detection on demand.
  11. Customizable electrochemical cells and battery molds tailored to user requirements.
• Standard configuration: reference electrode (Ag/AgCl or Ag⁺ electrode) & counter electrode (platinum wire electrode)
