采用高效液相色谱法，以甲醇＋酸水(体积比85∶15，水用磷酸调 pH 至3.0)为流动相，经ODS BP色谱柱分离，在260 nm波长下对45%唑醚·氟啶胺悬浮剂进行定量分析。结果表明，吡唑醚菌酯和氟啶胺的线性相关系数均为0.9998，变异系数分别为0.38%和0.44%，平均回收率分别为99.82%和99.79%。
採用高效液相色譜法，以甲醇＋痠水(體積比85∶15，水用燐痠調 pH 至3.0)為流動相，經ODS BP色譜柱分離，在260 nm波長下對45%唑醚·氟啶胺懸浮劑進行定量分析。結果錶明，吡唑醚菌酯和氟啶胺的線性相關繫數均為0.9998，變異繫數分彆為0.38%和0.44%，平均迴收率分彆為99.82%和99.79%。
채용고효액상색보법，이갑순＋산수(체적비85∶15，수용린산조 pH 지3.0)위류동상，경ODS BP색보주분리，재260 nm파장하대45%서미·불정알현부제진행정량분석。결과표명，필서미균지화불정알적선성상관계수균위0.9998，변이계수분별위0.38%화0.44%，평균회수솔분별위99.82%화99.79%。
A method was established for determination of pyraclostrobin + fluazinam 45% SC by HPLC, using methanol + acidic water (volume ratio of 85∶15) as mobile phase. The results showed that the linear correlation coefficients of pyraclostrobin and fluazinam were both 0.999 8, the variation coefficients were 0.38% and 0.44%, the average recoveries were 99.82%and 99.79%, respectively.
