摘  要:
采用高效液相色谱法测定20%氟铃·辛乳油中氟铃脲、辛硫磷的含量。以150mm×4.6mm(i.d.)不锈钢柱为色谱柱,内装C18填充物(粒径5μm);以乙腈-水(体积比为61∶39)为流动相,检测波长为254.32nm。结果表明,该方法测得氟铃脲、辛硫磷标准偏差分别为0.04、0.29,变异系数分别为1.7%、1.4%,线性相关系数分别为0.9992、0.9999,回收率分别为98.84%、99.25%。本方法操作简单、灵敏度高。

摘  要:
A method was introduced for the determination of hexaflumuron and phoxim by HPLC in hexaflumuron-phoxim 20% EC.Using a Eclipse XDB-C 18 column,methanol-water(61∶39,by vol)as mobile phase,and determination at 254.32 nm,the result showed that the standard deviations were 0.04 and 0.29,the coefficients of variation were 1.7 and 1.4,the linear relative correlations were 0.999 2 and 0.999 9,respectively.
