毛细管气相色谱法测定氟虱磺胺(SIOC-I-002)

Determination of SIOC-I-002 by Capillary Gas Chromatography

[目的]建立毛细管气相色谱法测定氟虱磺胺质量分数的方法。[方法]采用Rtx-5毛细管柱、FID检测器,以邻苯二甲酸二正丙酯为内标,以丙酮为溶剂。[结果]方法平均回收率为99.80%,标准偏差为0.13,变异系数为0.13%,线性相关系数为0.999 9。[结论]方法准确可靠、简便、快捷,可用于产品质量检测。

[Aims] The GC-NPD（gas chromatography-nitrogen and phosphorus detector） method for determination the residue of trifloxystrobin,its metabolite（CGA21113） and tebuconazole in banana and soil simultaneously was developed.[Methods] Trifloxystrobin,CGA21113 and tebuconazole were extracted from banana and soil sample with acetontrile and salted out with sodium chloride,then the samples were injected to the GC-NPD for analysis.[Results] The LOD of trifloxystrobin,CGA21113 and tebuconazole were 0.01,0.02 and 0.01 ng respectively.[Conclusions] The results showed that the method was convenient,fast,accuate with high accuracy and precision and good separating effect which was suitable for the determination of trifloxystrobin,CGA21113 and tebuconazole residues in banana and soil.
