โœฆ Synopsis

A method to analyse sulphate in beer in the presence of organic anions and sulphite has been developed using a Dionex Ion Chromatography system. Sulphite was stabilised in the sample by addition of acetaldehyde, 3.3% (v/v) and, by increasing the acetonitrile concentration of the eluant to 4.52 % (v/v), sulphate was separated from both malate and succinate without pre-treatment.

A method for the determination of organic acid anions in precipitation samples is described. The technique of ion chromatography exclusion (ICE) is used to identify and quantify the more commonly found anions of the acids citric, formic and acetic in central Illinois rainwater.
