CO2/O2 Off-gas Analyzer


  • Model No: FS-O-GA
  • Factory Location: Taiwan
  • Sample Request: No
  • Target Markets: Worldwide

Detail Information

Description :

The Winpact CO2/O2 off-gas analyzer provides real-time measurements of carbon dioxide and oxygen concentration of the bioreactor exhaust gas. The CO2 concentration is determined using a self-calibrating non-dispersion infrared sensor, while an electrochemical sensor monitors the oxygen concentration. Using this information, the user can continuously monitor metabolism and analyze cell growth parameters. The gas analyzer connects directly to the Winpact controller, allowing the user to observe, record, and export data for further analysis.
