Abstract: A satisfactory separation for 18 components of organophosphorus and 5carbamate insecticides on the OV-101 fused silica capillary column was gained. The average coefficient of variation of relative retention time (RRT) 0.446%; average fortified recoveries tested by two institutes were 93.56 ± 8.94% and 91.88 ± 7.62%, respectively; and the precision of the method within the permitting range. Besides the detection sensitivity, linear relationship is also inspected.

摘要: 对稻米中l8种农药包括有机磷类13种、有机氮类5种的残留分析方法研究结果表明,上述18个组分可在一根OV-l0l石英熔融毛细柱上获得较好的分离,相对保留值变异系数平均为0.468%;两个单位采用同种方法分析,添加回收率平均分别为93.56±8.94%和9l.88±7.62%,方法精密度、灵敏度及线性关系等均在允许范围之内。
