Determination of Ultra Low Content of Carbon in Iron by Ion-Chromatography

Autor: Ryo Inoue, Hideaki Suito, Ryozo Goto

Publikováno v: Materials Transactions, JIM. 34:528-532

A study on the determination or ultra low content of carbon was made by using ion-chromatography, coupled with the combustion method in oxygen gas stream. The considerable increase in the variation or conductivity with the content or carbonate ion wa

Determination of Ultra Low Content of Nitrogen in Metal and Slag by Ion-Chromatography

Autor: Takuma Kozono, Ryo Inoue, Ryozo Goto, Hideaki Suito

Publikováno v: Materials Transactions, JIM. 32:489-494

Effects of HCl, Fe, Na, and K in the determination of nitrogen as NH 4 + have been studied by the method of ion-chromatography. Analyzed value of nitrogen was reduced in the presence of HCl (≥9×10 -5 mol) and K (≥2 μg) in the injected solution,
