建立了在同一色谱条件下测定混剂中啶酰菌胺和腐霉利含量的方法。采用200mm×4.60mm(i.d.)SinoChrom ODS-BP柱分离,以乙腈-水(体积比为60∶40)为流动相,在225nm紫外检测波长下,经保留时间定性确证,峰面积外标法进行定量分析。结果表明:啶酰菌胺与腐霉利的线性相关系数分别为0.999 9和0.999 9;变异系数分别为0.34%和0.59%;平均加标回收率分别为99.32%和99.20%。
A method was established for the determination of boscalid and pythronate in the mixture under the same chromatographic conditions. (200) × 4.60mm (id) SinoChrom ODS-BP column with acetonitrile-water (60:40 by volume) as the mobile phase at 225nm UV detection wavelength, the retention time was qualitatively confirmed, the peak area of external standard method Quantitative analysis. The results showed that the linear correlation coefficients of boscalid and procymidone were 0.999 9 and 0.999 9 respectively, the coefficients of variation were 0.34% and 0.59%, respectively. The average recoveries were 99.32% and 99.20% respectively.
