The analysis of trace anions in concentrated nitric acid requires two online coupled ion chromatography systems for the required selectivity. The first system acts as preseparator of the trace anions from the matrix compounds. The trace anions are preconcentrated by means of a heart-cut valve and a
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/
