Abstract
THE conventional method of determining hydrogen in steel is vacuum extraction at 600°–700° C. Small specimens are heated, and the gases evolved are pumped off and collected in a suitable measuring system. It is generally accepted that the bulk of the hydrogen present in the steel is evolved under these conditions and that hydrogen is the principal component of the gases. Initially, separation of hydrogen from other gases was considered unnecessary1, but it has become common practice to pass the hydrogen through a palladium tube or to oxidize it with cupric oxide. The composition of the other gases, which may constitute 10–40 per cent of the total, is unknown, and there are considerable variations in analytical practice with regard to the elimination of moisture by freezing or reduction over ferro-manganese.
