Introduction

The method is used for the determination of the mass fraction of free lysine and its salts (including lysine hydrochloride and lysine sulfate) in fodder additives.

For the determination of free methionine, threonine and tryptophan in fodder additives use the method М 04-63-2016 (Lumex Instruments set, order No 0300002780).

For the determination of the mass fraction of lysine in feedstuffs, compound feeds, fodders, premixes, and all types of feed raw materials use the method M 04-38-2009 (Lumex Instruments kit, order No 0300002027).

The measurement method is based on capillary zone electrophoresis with indirect UV detection at the wavelength of 267 nm.
