| 摘 要： | 建立了固相萃取-气相色谱-质谱法快速检测毛豆中103种农药多残留的分析方法.样品用乙腈-水溶液均质提取,经盐析除水液液分配,Envi-18和PSA串联柱净化后用气相色谱-质谱仪(GC-MS)分析.采用选择离子扫描方式,外标法定量.方法的检出限(S/N=3)为0.001～0.021 mg/kg,在加标水平为0.2 mg/kg时,方法回收率为74%～123%,相对标准偏差为3.1%～13%.

| Abstract: | A method for the rapid determination of 103 pesticide multiresiduals in green soy bean by gas chromatography-mass spectrometry(GC-MS) with solid-phase extraction was proposed.The compounds were extracted from homogenized tissue with acetonitrile-water,separated with liquid-liquid partition.The clear supernatant liquid purified by solid phase extraction was ready for GC-MS analysis.Determinations were performed by using selected ion monitoring(SIM) mode and external standard method was used in the quantifica... |
