Sterilizable IR-ATR Fiber Probe for Bio-Process Monitoring

Sterilizable IR-ATR Fiber Probes are produced with any type of ATR element and for any type of FTIR spectrometers. Unique Shaft-in-Shaft design of the IR-ATR Fiber Probes makes them perfect for bioprocesses where sterilization is required without having to forgo the renowned advantages of MID-IR FTIR spectroscopy.
The IR-ATR Fiber probes do have to be taken out from the reactor during the reactor sterilization process. The sensitive tip of the probe can remain in the reactor and be sterilized with it, whereas the fiber assembly can be detached.

  • High throughput in any part of near and mid-infrared-spectrum
  • ATR-tip shaped for immersion in the liquid flow without a dead zone
  • Flexible and robust for industrial applications in harsh environment
  • Compatible with all spectrometers and automated process-interfaces
  • Reaction monitoring in real time
  • Process analytical technologies (PAT)
  • Remote polymerization control
  • Crystallization process screening
  • In-situ IR-spectroscopy for PAT in chemical, petrochemical, atomic, biopharmaceutical and Food industry
