Indirect Suppressed-Conductivity Ion Chromatography

The authors demonstrate a new detection method, indirect suppressed conductivity, for various anions of weak acids separated by ion chromatography. They analyzed three groups of anions, including amino acids such as leucine, taurine, phenylpropionic acid, and phenol; malic and tartaric acids; and lactic, formic, and benzoic acids. The authors describe the mobile phases, detection limits, and correlation coefficient of rectilinear relationships for each anion type.
