CHEMICAL-ELECTRICAL SENSING.

Abstract

An investigation was conducted to determine the feasibility of using krypton-85 homologs to detect trace quantities of hydrogen chloride and hydrogen fluoride in air. Zinc foil kryptonates were found to respond well to low hydrogen chloride concentrations and thus can serve as detectors. Calibration curves are presented for the range of hydrogen chloride concentrations from 97 ppb to 250 ppm for exposure times up to 3 hours. Relative humidity had no significant effect on the detection sensitivity. Aluminum and copper kryptonates showed satisfactory response to a hydrogen fluoride concentration of 263 ppm. A flow system for obtaining lower concentration was constructed. (Author)
