摘要
建立了一种以液相微萃取(Liquid Phase Microextraction,LPME)与气相色谱-氢火焰(LPME-GC-FID)联用技术为基础的测定尿样中氨基比林、安替比林和巴比妥的方法。考察了萃取溶剂、萃取时间、pH对萃取效果的影响。氨基比林、安替比林、巴比妥线性范围分别为1.67-333、133-667、60-300 mg/L,检出限分别为1、4、12 mg/L。
A method based on liquid phase microextraction (LPME) with gas chromatography-flame ionization detector (GC-FID) was established for the determination of aminopyrine, antipyrine and barbital in Urine. The effects of extraction solvent, extraction time and pH on the extraction efficiency were investigated. The linear ranges for aminopy- fine, antipyrine and barbital were 1.67 - 333 mg/L, 133 - 667 mg/L, 60 - 300 mg/L respectively. The detection limits for them were 1, 4, 12 mg/L respectively. It indicated that LPME is a promising sample preparation method for analysis in forensic science.
