【摘要】 用反相液相色谱建立了分析除草剂盖草能含量的方法，采用ＯＤＳ－Ｃ１８柱（２５０ｍｍ×４．００ｍｍｉ，ｄ），以乙腈－水（７３∶２７）为流动相，用紫外２４０ｎｍ检测，本方法的线性实验，回收率实验、精密度实验均良好，产品测定的变异系数为０．６７％，小于１．５０％。更多还原

【Abstract】 An RP-HPLC method for fhe quantitative determination of Haloxyfop-methyl. has been developed. Operating conditions were ODS-C 18 Column. 250mm×4.0 mm i.d. acetonitrile-watr (73.27) eluent and UV-240 nm dection The method is reproducible and coefficient of variation was less than 1.50%.更多还原
