摘要
采用高效液相色谱法,用C18(ODS)柱为分离柱、甲醇-0.5%冰乙酸溶液为流动相、紫外检测器、外标法分析,测定2-氯吡啶的含量。本方法的标准偏差为0.12,变异系数为0.13%,回收率为99.86%~100.91%,线性相关系数为0.9998。
Abastract: A quantitative analysis mothod of the clopyralid was established by HPLC with ODS column and methanol:0.5% solution of glacial acetic acid as mobile phase.Results showed that recovery was 99.74%~100.67%,the standand deviation was 0.12 and the variation cofficient was 0.13%. linear correlation coefficient was 0.9998.
