0.5% dimethyl disulfide EC is a new and efficient broad spectrum acaricide, with high activity, fast insecticidal characteristics and control effect on the control of cotton red, white and yellow spider, rust mite, cotton leaf mite eggs, larvae and adults were very high. At present, there is no uniform standard for the country to carry out the inspection, access to the relevant literature, has not yet seen the report of the analysis method.
Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus gas chromatography, with dimethyl sulfide as internal standard, packed column and FPD detector using nitrile, on samples of dimethyl disulfide for separation and quantification. The results showed that the linear correlation coefficient was 0.9999, the standard deviation was 0.0040, the coefficient of variation was 0.75%, the average recovery rate was 99.63%, the coefficient of variation was two and the average recovery rate was two. The method is simple, rapid and accurate.
0.5%二甲基二硫醚乳油是一种新型、高效的广谱杀螨剂,具有活性高、杀虫快等特点,对防治棉花白红黄蜘蛛、锈蜘蛛、棉叶螨等的卵、幼虫、成虫均有很高的防治效果。目前,国家还没有统一的标准对其进行检验,查阅相关文献,尚未见其分析方法的报道。
滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱法,以甲硫醚为内标物,使用腈填充柱和FPD检测器,对试样中的二甲基二硫醚进行分离和定量。分析结果表明:二甲基二硫醚的线性相关系数为0.9999,标准偏差为0.0040,变异系数为0.75%,平均回收率为99.63%。方法简便、快速、准确。
