The most convenient method of determining traces of hydrogen in metals is the method of vacuum heating. The metal sample is placed in a quartz exchange-reactor and the air is pumped out of this. For temperatures of up to 650°C, only hydrogen evolves from the metal [1]; for higher temperatures, up to 1100°C, carbon monoxide, nitrogen, and carbon dioxide also appear [2], For example, mass-spectrometric analysis of the composition of the gas evolved from a sample at t = 900°C gave the results: H2 — 70.3%; CO — 24.3%; C02 — 0.27%; and nitrogen 5.03%.
