Excerpt from Gases in Metals, Vol. 2: The Determination of Oxygen and Hydrogen in Metals by Fusion in Vacuum
The presence of oxygen, hydrogen, and nitrogen in small amounts in most commercial metals is well known.

In such cases it is often felt that differences in the' 'gas content of the material are of significance. The term gas used m this manner indicates those substances found in metals in either coin bined or 'uncombined Condition which, in their ordinary free state, exist as gases. The expressmn thus includes oxides, hydri'des, 'and nitrides 111 metals as well as uncombined oxygen, nitrogen, hydrogen, or other gases.
