The limits of gas-chromatographic detection of neon, hydrogen, argon, nitrogen, krypton, and methane in helium have been determined using a helium ionization detector under saturation current conditions. The detection limits are restricted by the gas permeability of the detector Teflon body and the injection system. The dependence of extraction of impurity gases by cryogenic adsorption enrichment on their contents and enrichment time has been examined. the relative detection limit can be lowered by preconcentration of 3 x 10/sup -5/% for neon and to 4 x 10/sup -7/ to 2 x 10/sup -8/% for other gases.
