✦ Synopsis

Abstract

An ion chromatographic procedure (IC) with chemical suppression is described for the simultaneous determination of the anions Cl^−^, NO, HPO and SO at ppm levels in vinegar samples. The moderately strong eluent composed of NaHCO~3~/Na~2~CO~3~ was chosen and sample pretreatment was required to reduce the influence of acetate on the chloride peak. The results obtained by IC were compared to those from standard methods.
