原理 尿样经蒸馏法处理,再用乙醚萃取后经双-(对己氧基苯甲酸)邻甲基对苯二酚酯色谱柱分离,用氢火焰离子化鉴定器测定。 仪器 1.气相色谱仪具氢火焰离子化鉴定器 2.μl微量注射器 3.蒸气蒸馏装置(图1)
Principle Urine samples were treated by distillation, extracted with diethyl ether and separated by o- (p-hexyloxybenzoic acid) o-methyl hydroquinone ester column, and determined by hydrogen flame ionization detector. Instruments 1. Gas Chromatography with flame ionization identification 2.μl micro-syringe 3. Steam distillation unit (Figure 1)
