重Analytical EquipmentHIGH PERFORMANCECAPILLARYELECTROPHORESIS DETERMINATION OF ANIONS IN FEEDSTUFFS，COMPOUND FEEDS， AND FEED RAW MATERIALS Lumex Method M 04-73-2011 INTRODUCTION The method is used for the determination of the mass fraction of water-soluble chloride， nitrate， phosphate，and total sulfate in all types of feedstuffs， compound feeds， fodders， premixes， fodder additives， andfeed raw materials (of plant， animal， and mineral origin) by capillary electrophoresis. 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. Compound Measurement range*， % Chloride 0.005-60 Nitrate 0.002-1.0 Phosphate 0.005-80 Sulfate 0.005-70 *For the sample weight of 100-500 mg. The determination of phosphate is not hindered by the presence of carbonate (with mass concentration ratioof 10：1) and all other analytes (with mass concentration ratio of 1000：1). The determination is not hinderedby the presence of other inorganic anions， organic acids (acetic， citric， lactic， formic， oxalic) and neutralorganic substances. 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. Lumex Instruments set， order No 0300001921.
