对稻米中18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—101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91.88±7.62%,方法精密度、灵敏度及线性关系等均在允许范围之内。
18 rice pesticides including 13 kinds of organic phosphorus, organic nitrogen 5 kinds of residue analysis method results show that the above 18 components in a OV-101 fused silica capillary column to obtain a better separation, relative The average coefficient of variation (CV) of retention values was 0.468%. The average recoveries of two units were 93.56 ± 8.94% and 91.88 ± 7.62%, respectively. The precision, sensitivity and linearity of the methods were within the allowable range.
