ABSTRACT:
An arrangement in which samples drawn from a melt are sealed against air, and are allowed to solidify, while the gases given off are collected for analysis. A hollow, thin-walled, metallic element is used, which narrows at its lower end into an orifice. The element is degassed at high temperature before being sealed for use, to remove hydrogen and organic impurities.
