Analysis of the anions originating from the brewing liquor itself or from the raw materials and processing aids used in the production of beer or other beverages
This method is suitable for the determination of anions (chloride, sulfate, nitrate, phosphate) in beer samples and other beverages by means of ion chromatography.
The anions chloride, sulfate, nitrate and phosphate are separated by means of ion chromatography. The conductivity detection with a suppressor provides quantitative information about the anions. The concentrations are calculated by means of the individual areas under the peaks from the chromatogram with reference to calibration factors.
