Determination of anions in feedstuffs, compound feeds, and feed raw materials

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, and feed raw materials (of plant, animal, and mineral origin) by capillary electrophoresis.

MEASURING METHOD

The measurement method is based on capillary zone electrophoresis with indirect UV detection at the wavelength of 254 nm.
