ResumoA rapid ion chromatographic method for the determination of carbohydrates in samples collected at all stages of beer production is described. Carbohydrates were separated by direct-injection anion exchange chromatography on a polymeric non-porous pellicular resin column (Dionex Carbopac PA1) and detected by pulsed amperometric detection at a gold working electrode. The method offered distinct advantages in terms of selectivity and sensitivity when compared with alternative normal-phase HPLC methodology. Applicability of the method to the analysis of brewing syrups, dairy milk, and soft drinks, in addition to beers and worts, was demonstrated.
