Ähnlich wie Stickstoff, der auch als gewünschter Legierungsbestandteil auftreten kann, führen Wasserstoff und Sauerstoff schon in geringsten Mengen zu einer ausgeprägten Versprödung des Stahls. Die Gasheissextraktionsanalyse ist ein zuverlässige Verfahren diese Elemente in Eisen und Nichteisenmetalle mit höchster Genauigkeit und Reproduzierbarkeit in kleinsten Konzentrationen zu bestimmen.

In most cases it is not so much the concentrations of the desired alloying elements that are responsible for the steel quality, but the presence of undesirable foreign elements. Nitrogen, for example, which on occasion appears as a desirable alloying constituent, hydrogen and oxygen in very small concentrations can lead to a pronounced embrittlement of a steel. Hot gas extraction analysis is a reliable procedure with which smallest concentrations of these elements can be determined with high accuracy and reproducibility in ferrous and non-ferrous alloys. As a result of these capabilities, hot gas extraction analysis is applied effectively in the research and development arena as well as in quality control. The measurement ranges are 0.1 – 250 ppm for elemental hydrogen, 0.5 ppm – 0.2% for elemental oxygen and 0.5ppm – 3.0% for elemental nitrogen.
