Abstract

A method and an apparatus for continuously measuring the hydrogen concentration in argon gas containing hydrogen and other impurities. The argon gas containing impurities is continuously passed through a high temperature metal getter to thereby remove impurities other than hydrogen from the argon gas and produce a two-component mixture of gases consisting of argon and hydrogen. The two-component gas is then continuously introduced to a thermal conductivity detector and the hydrogen concentration can be determined from the detected thermal conductivity.
