饲料添加剂中赖氨酸及其盐类检测方案(毛细管电泳仪)

重Analytical Equipment一、寸曾www.lumexinstruments.ccm series DETERMINATION OF LYSINE AND ITS SALTSIN FODDER ADDITIVES Lumex Method M 04-87-2016 INTRODUCTION The method is used for the determination of the mass fraction of free lysine and its salts (including lysinehydrochloride and lysine sulfate) in fodder additives. For the determination of free methionine， threonine and tryptophan in fodder additives use the methodM 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 alltypes of feed raw materials use the method M 04-38-2009 (Lumex Instruments kit， order No 0300002027). MEASUREMENT METHOD The measurement method is based on capillary zone electrophoresis with indirect UV detection at thewavelength of 267 nm. MEASUREMENT RANGE The measurement range for lysine is 30-100%. 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 0300002726.
