ABSTRACT:
A sampling device for a quantitative determination of hydrogen in molten metal, which includes a material in which hydrogen is relatively non-diffusible during testing or readily soluble during sampling and a refractory vessel housing this material. This refractory vessel is sealed so as to maintain a vacuum or negative (reduced) pressure therein, and is provided with a thin-walled aspirating portion which is readily destroyed by an external pressure.
