pyraclostrobine%fluazinam%LC
建立了在同一色谱条件下测定混剂中吡唑醚菌酯和氟啶胺含量的方法。采用200 mm×4.60 mm(i.d.) Hypersil BDS-C18柱分离,以甲醇-水-磷酸(体积比为85:15:0.02)为流动相,在260 nm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。吡唑醚菌酯与氟啶胺的线性相关系数分别为1.0000和1.0000;变异系数分别为0.29%和0.36%;平均回收率分别为99.57%和100.07%。该方法操作简便快捷,准确度和精密度高,线性相关性好。
建立瞭在同一色譜條件下測定混劑中吡唑醚菌酯和氟啶胺含量的方法。採用200 mm×4.60 mm(i.d.) Hypersil BDS-C18柱分離,以甲醇-水-燐痠(體積比為85:15:0.02)為流動相,在260 nm紫外檢測波長下,經保留時間定性確證,峰麵積外標法進行定量分析。吡唑醚菌酯與氟啶胺的線性相關繫數分彆為1.0000和1.0000;變異繫數分彆為0.29%和0.36%;平均迴收率分彆為99.57%和100.07%。該方法操作簡便快捷,準確度和精密度高,線性相關性好。

A LC method for the determination of pyraclostrobine and fluazinam SC was developed. The LC conditions were Hypersil BDS-C18 column, methanol-water-phosphorous acid(85:15:0.02 byvol) as mobile phage, and detection wave length at 260nm. The results demonstrated that the correlation coefficients of pyraclostrobine and fluazinam were1.0000 and 1.0000. The variation coefficients were0.29% and 0.36%. The average recoveries were 99.57% and 100.07%. The method is simple, rapid, accurate and suitable for analysis of this kind of multiplex confected preparation.
