FI-RXF100-G
FI-RXF100-G Portable High-Temperature FTIR Gas Analyser
A compact FTIR gas analyser with an integrated multi-pass gas cell of 5–9.8 m path length, heated to 180 °C. A dedicated coupling chamber joins spectrometer, gas cell, temperature controller, thermocouple and heat sink, so the beam path is short and practically unaffected by the ambient atmosphere.

Overview
About the FI-RXF100-G
Easy to use, capable, compact and robust: the FI-RXF100-G is an infrared spectrometer that anyone can use, anywhere. A practically maintenance-free optical system and a proven interferometer design give accurate, repeatable measurements day after day, and its fully integrated, reliable sampling and portable accessories suit it to the laboratory and to field testing.
The compact gas analyser integrates a long-path gas cell. A purpose-designed coupling chamber combines the spectrometer with the gas cell, temperature controller, thermocouple and heat sink, so the beam path is short and practically unaffected by the surrounding atmosphere. The online system is designed for waste incineration and online environmental gas monitoring.
