Use of a Palladium Tube in Gas Analysis

Abstract

4 method of analysis for gas mixtures which consist largely-of hydrogen and of small amounts of carbon monoxide, nitrogen, methane, and higher hydrocarbons is described. The higher molecular h ydrocarbons are frozen at -180" C. and the hydrogen is removed by diffusion through a palladium tube at 300" C. The carbon monoxide and the methane are then burned S THE course of a n investigation of the effect of corona I discharge on insulating oil, it was necessary to obtain an accurate knovledge of the composition of the generated gas. This type of gas mixture is largely hydrogen with a small amount, not over 5 per cent by volume, of niethane and higher molecular hydrocarbons, a still smaller amount of carlion monoxide, not over 1 per cent by volume, and nitrogen, T I ith no oxygen present. The conventional method of
