采用高效液相色谱法，以甲醇＋0.5%冰乙酸水溶液(体积比60︰40)为流动相，使用ZORBAX SB-C18不锈钢色谱柱和紫外阵列检测器，在254 nm波长下测定10%二氯·五氟悬浮剂中有效成分质量分数。结果表明：二氯喹啉酸和五氟磺草胺的标准偏差分别为0.0192、0.0167，变异系数分别为0.23%、1.13%，平均回收率分别为99.43%、99.51%，线性相关系数分别为1.0000、0.9999。
採用高效液相色譜法，以甲醇＋0.5%冰乙痠水溶液(體積比60︰40)為流動相，使用ZORBAX SB-C18不鏽鋼色譜柱和紫外陣列檢測器，在254 nm波長下測定10%二氯·五氟懸浮劑中有效成分質量分數。結果錶明：二氯喹啉痠和五氟磺草胺的標準偏差分彆為0.0192、0.0167，變異繫數分彆為0.23%、1.13%，平均迴收率分彆為99.43%、99.51%，線性相關繫數分彆為1.0000、0.9999。
채용고효액상색보법，이갑순＋0.5%빙을산수용액(체적비60︰40)위류동상，사용ZORBAX SB-C18불수강색보주화자외진렬검측기，재254 nm파장하측정10%이록·오불현부제중유효성분질량분수。결과표명：이록규람산화오불광초알적표준편차분별위0.0192、0.0167，변이계수분별위0.23%、1.13%，평균회수솔분별위99.43%、99.51%，선성상관계수분별위1.0000、0.9999。
A method for separation and quantitative analysis of quinclorac + penoxsulam 10% SC was described by HPLC on ZORBAX SB-C18 column with UV detector at 254 nm, using methanol and acetic aqueous solution as mobile phase. The results showed that the standard deviations of quinclorac and penoxsulam were 0.0192, 0.0167, the coefficients of variation were 0.23%, 1.13%, the average recoveries were 99.43%, 99.51%, and the linear correlation coefficients were 1.0000, 0.9999, respectively.
