the determination of diethylstilbestrol (DES) in aquatic products by high performance liquid chromatography (HPLC) using a fluorescence detector (FLD) was developed. By means of sulfonation in concentrated sulfuric acid and hydrolysis, DES was converted into a reaction product that can emit fluorescence and determined by HPLC. For the first time, HPLC with FLD was applied to the determination of DES
建立了一种灵敏的方法,通过使用荧光检测器(FLD)的高效液相色谱(HPLC)测定水产品中的己烯雌酚(DES)。通过在浓硫酸中进行磺化和水解,将DES转化为可发出荧光的反应产物,并通过HPLC测定。首次将带FLD的HPLC用于DES的测定,其灵敏度与获得的LC-MS相当。检出限为0.1 µg·kg -1,回收率在86%以上,相对标准偏差小于6.2%。该方法已成功应用于水产品中DES的测定。
