Fiber Optic ATR-Probes for Harsh Environment

  • High throughput in selected parts of Near & Mid InfraRed-spectra
  • ATR-tip shaped for immersion in liquid flow without dead zone
  • Robust for industrial applications in harsh environment up to 250°C
  • Resistant to high pressure
  • Compatible with all spectrometers and automated process-interfaces

FlexiSpec® probes from art photonics include new type of Attenuated Total Reflection (ATR-) probes designed for harsh application conditions.
HT-ATR immersion IR-fiber probes can be used for process-spectroscopy in Near & Mid IR range to monitor reactions in-line in a broad temperature range from -100° to +250°C. They can resist to high pressures up to 200Bar and used with FTIR or any other IR-spectrometers and spectral sensors in automated process control with process-interfaces.
  • Remote Reaction Monitoring in-line in temperature range -100/+250°C
  • PAT applications in lab, pilot plant or industry with process-interfaces for automated process control
  • Polymerization Process Control
  • In-situ IR-Spectroscopy for PAT in Chemical, Petrochemical, Atomic, Biopharmaceutical & Food Industry
