Abstract

An infrared absorption method in the 1- to 15-μ range has been developed for determining HF, HCl, HCF₃, and SiF₄ in WF₆ gas. Because of the reactivity and corrosiveness of WF₆, a special gas absorption cell and gas-sampling apparatus were designed and built. Calibration curves were generated for a 10-cm cell. Sensitivity values were 100 wppm for HF and HCl, and 10 wppm for HCF₃ and SiF₄.
