Abstract
Assesses three methods for determining the hydrogen content in metallic materials: optical emission, heating in a carrier inert gas with a conductometric termination, and vacuum heating with a mass spectrometric end. Also considers the optimal scope of each of the considered methods for solving specific problems aimed at determining the hydrogen content with different binding energies (common, diffusion-mobile, strongly bonded) in metallic materials.
