Electrolytic Conductivity Detector for Trace Analysis of H2, HD, D2, and Neon in Hydrogen and Deuterium

SLAC-PUB-1667 (Rev.) November 1975 Revised May 1976 (1) ELECTROLYTIC CONDUCTIVITY DETECTOR FOR TRACE ANALYSIS OF HZ, HD, D2, AND NEON IN HYDROGEN AND DEUTERIUM” E. L. Garwin and A. Roder Stanford Linear Accelerator Center Stanford University, Stanford, California 94305 A gas chromatograph has been developed to detect traces of H2, HD, D2, and neon in hydrogen or deuterium. It uses a stainless steel column packed with ferric chloride-treated alumina, hydrogen-doped helium carrier gas, palladium chloride to convert the eluted components into their corresponding chlorides, and an electrolytic conductivity cell to measure the chloride concentration. The detection limits of the instrument are 0.01% H2 in D2, .0.02% D2 in H2, and 0.02% HD in either gas. (Submitted to J. Chromatog.
