cyazofamid%fluazinam%HPLC%analysis
采用高效液相色谱法，以乙腈＋冰乙酸水溶液(pH＝3.0，体积比40∶60)为流动相，经ODS-BP色谱柱分离，在280 nm波长下对40%氰霜·氟啶胺悬浮剂进行定量分析。结果表明：氰霜唑和氟啶胺的线性相关系数分别为0.9999和0.9998，变异系数分别为0.43%和0.23%，平均回收率分别为99.52%和99.80%。
採用高效液相色譜法，以乙腈＋冰乙痠水溶液(pH＝3.0，體積比40∶60)為流動相，經ODS-BP色譜柱分離，在280 nm波長下對40%氰霜·氟啶胺懸浮劑進行定量分析。結果錶明：氰霜唑和氟啶胺的線性相關繫數分彆為0.9999和0.9998，變異繫數分彆為0.43%和0.23%，平均迴收率分彆為99.52%和99.80%。
채용고효액상색보법，이을정＋빙을산수용액(pH＝3.0，체적비40∶60)위류동상，경ODS-BP색보주분리，재280 nm파장하대40%청상·불정알현부제진행정량분석。결과표명：청상서화불정알적선성상관계수분별위0.9999화0.9998，변이계수분별위0.43%화0.23%，평균회수솔분별위99.52%화99.80%。
A method was established for determination of cyazofamid +fluazinam 40% SC by HPLC on ODS-BP column with DAD at 280 nm, using acetonitrile + acetic acid aqueous solution (pH=3, volume ratio of 40︰60). The results showed that the linear correlation coefficients of cyazofamid andfluazinam were 0.9999 and 0.9998, the variation coefficient were 0.43% and 0.23%, the average recoveries were 99.52% and 99.80%.
