The Hydrogen Analysis of Solid Samples

By Morinobu Hayashi


Each year the marketplace sees increasing demands for the analysis of hydrogen contained in various sample materials. It is now recognized that hydrogen analysis is crucial not only in the steel industry but also in the manufacture of such high purity metals as aluminum, copper, titanium and in the development of new alloys and new materials. To meet these demands, Horiba has developed and marketed two models of a new type of hydrogen analyzer with a flexible power control function, the EMGA-521 and the EMGA-621. This report discusses the design and principle of measurement of the new hydrogen analyzer, using data from actual measurements. Also introduced here is the behavior of the hydrogen content of the sample when the flexible power control function of the analyzer is used and the importance of sample pre-treatment in hydrogen analysis.
