Studies on the Analysis of Cations by Ion Chromatography

Many studies on the analysis of cations in blood have been reported. However, no suitable method for the pretreatment of blood for the determination of cations by Ion Chromotography. As a result, pretreatment method that the membrane filtration of plasma a diluted 1 to 100 fold acidified pH 3.5 was found to be the most suitable. The recoveris of monovalent cations in blood were yield 101%(Na$^{+}$). 102%(NH$^{+}_{4}$) and 101%(K$^{+}$) Determinations of divalent cations(Mg and Ca ions) in blood by Ion chromatography were summarized as followed conditions Separator Column : CS$_{3}$. Suppressor Column : CMMS. Eluent conen : 25m M-HCl/2mM-Histidine. Regenerant conen: 40mM-Ba(OH)$_{2}$.
