摘要
用３％ＯＶ－１０１２ｍ×３ｍｍｉ．ｄ．玻璃或不锈钢柱，以邻苯二甲酸二（２－乙基）己酯为内标，在柱温２２３℃时同时测定氯菊酯胺菊酯混合防蛀剂中有效成分——氯菊酯和胺菊酯的质量分数。方法中氯菊酯和胺菊酯的平均变异系数分别为０．２０％和０．１９％。
Mixed mothproofer of permethrin and tetramethrin is a new formulation for prevention cloth moth in China. A rapid and specific method is needed to simultaneously determine these two active ingredients. For this purpose, a method by GC was established with a 3% OV 101/Chromosorb WAW DMCS(180 250 μm) column at a temperature of 223 ℃, by using di iso octylsebacate as internal standard. The mean coefficient of variation for permethrin and tetramethrin were 0.20% and 0.19% respectively. Linearity of detector response vs. mass concentration ranged from 0.38 2.6 g/L with r=0.999 9
