INTRODUCTION

The method is used for the determination of the mass fraction of phosphates (phosphorus, P) in samples of drinking milk, cream and dairy raw materials (raw and concentrated milk, milk powder; raw cream and cream powder) by capillary electrophoresis.

MEASURING METHOD

The measurement method is based on extraction of phosphates from a solid sample by water (or dilution of a liquid sample) and their determination by capillary electrophoresis with indirect UV detection at the wavelength of 254 nm.
