Determination of hydrogen in metals by a combination of the so-called carrier gas method and the technique of frontal chromatography

“…RECEIVED for review June The determination of hydrogen in metals, particularly in steels, belongs to the basic metallurgical analyses (1,2). Most of the methods are based on the extraction of hydrogen in vacuum at higher temperatures (600-1200 °C) and its separation and determination, frequently with the use of gas chromatography (2)(3)(4)(5). The finding that the extraction of hydrogen is feasible practically under about atmospheric pressure by the so-called carrier gas method (6) can markedly simplify the instrumental arrangement.…”
