摘 要:
采用高效液相色谱法测定饲料中三聚氰胺含量。色谱柱为Waters Xterra柱(4.6mm×150mm,5μm);流动相为乙腈:10mmol/L辛烷磺酸钠-柠檬酸缓;中液(10:90,V:V),检测波长为240nm,流速1.0mL/min,进样量20μL,保留时间约6.23min。三聚氰胺在1.0-50μg/mL范围内具有良好的线性关系(R2=0.99996),在添加浓度为20-100mg/kg范围内,三聚氰胺添加回收率在90%-95%,RSD小于5%。[著者文摘]

Abstract:
A high performance liquid chromatographis method was developed for the determination of melamine content in feed, using Waters Xterra column(4.6 mm × 150 mm,5μn) , actonitrile and 10 mmol/L Sodium 1 - Octanesulfonate-citric acid Solution (10:90, V:V) were used for this method. The result showed that testing wave was at 240 nm. The retention time was about 6.23 min. The standard curve was between 1.0 μg,/mL and 50 μg,/mL(R^2 = 0.99996). And the recoveries at three fortification levels(20,50,100 mg,/kg)were 90% - 95% with RSD〈 5%.[著者文摘]
