	Far Infrared Spectroscopy (Far-IR) is a bend magnet infrared beamline at the Canadian Light Source. The beamline utilizes a gas cell loaded with experimental gas which light is bounced through and a spectrometer to measure the absorption of the gas. For an experiment at Far-IR utilizing methane and nitrogen at 100K temperatures, issues with icing and inconsistent absorption gradients were noted at the Polymethylpentene Rigid Plastic (TPX TM) window separating the cell filled with the flammable gas mixture from the vacuum of the spectrometer. The possibility of replacing the existing windows with new 50-micron thick polypropylene windows was investigated. Material properties were not available for polypropylene at the operating temperature of the experiment. Due to the hazardous nature of the gas being held back a hazard analysis was carried out to identify potential risks and mitigations for the change. Additionally, with material properties unavailable, a testing regime was established to ensure the polypropylene could survive in the experimental environment. The experiment was successfully completed using the modified window assemblies.

Far Infrared Spectroscopy (Far-IR) is a bend magnet infrared beamline at the Canadian Light Source. The beamline utilizes a gas cell loaded with experimental gas which light is bounced through and a spectrometer to measure the absorption of the gas. For an experiment at Far-IR utilizing methane and nitrogen at 100K temperatures, issues with icing and inconsistent absorption gradients were noted at the Polymethylpentene Rigid Plastic (TPX TM) window separating the cell filled with the flammable gas mixture from the vacuum of the spectrometer. The possibility of replacing the existing windows with new 50-micron thick polypropylene windows was investigated. Material properties were not available for polypropylene at the operating temperature of the experiment. Due to the hazardous nature of the gas being held back a hazard analysis was carried out to identify potential risks and mitigations for the change.
