重Analytical Equipment一寸丁<、www.lumexinstruments.ccm DETERMINATION OF ANIONS IN BEVERAGESLumex Method M 04-79-2013 INTRODUCTION The method is used for the determination of the mass concentration of chloride， sulfate， and nitrate inbeverages by capillary electrophoresis. The method can be applied for all types of non-alcoholic andalcoholic beverages including sport and energetic drinks， juices， beer and beer products， wines，brandy and spirits， liquors， and vodka. MEASUREMENT METHOD The measurement method is based on capillary zone electrophoresis with indirect UV detection at thewavelength of 254 nm. MEASUREMENT RANGE The measurement ranges for the components are presented in the table below. Anions Measurement range， mg/L Chlorides 0.5-20000 Sulfates 0.5-5000 Nitrates 0.5-500 Other inorganic anions (nitrite， bromide， sulfite，fluoride， phosphate， and carbonate) and organic acids (acetic，tartaric， oxalic， malic， citric and others) in concentrations， typical for the mentioned beverages do notdeteriorate target anions determination. EQUIPMENT AND REAGENTS The CAPEL capillary electrophoresis system is used in measurements. Data acquisition， collection，processing and output are performed using a personal computer running under WINDOWS@ XP/7/8/10operating system with installed dedicated software package ELFORUN.
