Abstract

Trace moisture and other potential impurities (CO2, CH4, C2H6, and alkyl halides) in HCl and in HBr gases were analyzed by gas-phase FTIR spectroscopic technique. The detection limit was estimated to be 100 ppb with 2 cm−1 spectral resolution for 5-min measurement time at 1.2 kg cm−2 pressure, using an MCT detector and an 8-m-pathlength gas cell with BaF2 windows.
