Analytical EquipmentHIGHPERFORMANCECAPILLARY ELECTROPHORESISSYSTEMwww.lumexinstruments.ccm DETERMINATION OF SYNTHETIC AMINO ACIDS (METHIONINE， THREONINE， TRYPTOPHAN) IN FODDER ADDITIVES Lumex Method M 04-63-2016 INTRODUCTION The method is used for the determination of the mass fraction of free methionine， threonine， and tryptophanin fodder additives. For the determination of the mass fraction of methionine， threonine， and tryptophan in feedstuffs， compoundfeeds， fodders， premixes， and all types of feed raw materials use the method M 04-38-2009 (LumexInstruments kit， order No 0300002027). For the determination of free lysine in fodder additives use the method M 04-87-2016 (Lumex Instrumentsset， order No 0300002726). For the determination of methionine hydroxy analogue (HMTBa) in fodder additives use the methodM 04-83-2014 (Lumex Instruments set， order No 0300001888). MEASUREMENT METHOD The measurement method is based on capillary zone electrophoresis with direct UV detection at thewavelength of 200 nm. MEASUREMENT RANGE The measurement ranges for components are 80-100%. 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 0300002780.
