Simultaneous determination of selected transition metal cations and inorganic anions by ion chromatography

Abstract

The retention times and detection limits of a selected group of six transition metal cations and four inorganic anions determined using a simultaneous separation and detection system are presented. The over-all analysis time is usually less than 20 min and detection limits are at or near the 1 p.p.m. level. Two different systems are described, the first for the repetitive analysis of similar solutions and the second for samples of widely varying composition.
