Determination of hymexazol in agricultural products by GC-NPD
Tamura Y, et al.;
Shokuhin Eiseigaku Zasshi. 2008 Jun;49(3):223-7
Abstract:
A method for the determination of hymexazol in agricultural produdcts by gas chromatography with a highly sensitive nitrogen-phosphorus detector (GC-NPD) was investigated. Hymexazol was extracted with acetonitrile, and the acetonitrile layer was separated by salting-out. The water layer was loaded onto a Chem-Elut column. Hymexazol in the water layer was adsorbed on the column, and eluted with ethyl acetate. The acetonitrile layer and the eluate were mixed and evaporated. The residue was dissolved in ethyl acetate, and the sample solution was cleaned up on a C18 column. Hymexazol in the eluate was analyzed by GC-NPD with a high-polarity capillary column (DB-FFAP) and highly deactivated inlet liner.Recoveries of hymexazol spiked in agricultural products (tomato, lemon, soybean and other samples) at the level of 0.1 mug/g ranged from 65.0 to 84.7%. The limit of detection was 0.02microg/g.

恶霉灵、甲霜 灵复配制剂的高效液相色谱分析
摘  要:本文报道杀菌剂恶霉灵和甲霜灵复配制剂的液相色谱分析方法。选用PR00IGY-ODS(3)为固定相,甲醇-水(70:30)为流动相。紫外检测波长212nm,流速为1.00ml/min。恶霉灵和甲霜灵的变系数分别为2.37%和2.92%,平均回收率分别为98.91%和97.27%,标准偏差小于0.25。线性相关系数分别为0.9910、0.9819。

gc-npd检测方法比较多


GC上恶霉灵峰可能拖尾比较严重
