研究超声波提取、大口径毛细管气相色谱配氮磷检测器 (NPD) ,检测棉籽中丙硫克百威及其代谢物残留。各组分回收率 83%～ 110 % ,线性范围 10 3,最低检出浓度 0 .0 2～ 0 .0 1mg/kg。本方法具有简单、快速、省试剂的特点。
To study the ultrasonic extraction and large-bore capillary gas chromatography coupled with nitrogen and phosphorus detector (NPD), and to detect the residues of propylthiouracil and its metabolites in cottonseed. The recovery rate of each component was 83% ~ 110%, the linear range was 10 3, the lowest detected concentration was 0 .0 2 ~ 0. 1 mg / kg. The method has the characteristics of simple, rapid and reagent-saving.
