建立了分散固相净化-气相色谱法同时检测蔬菜中氟吡菌胺、唑菌酮和茚虫威等15种残留农药的分析方法。样品经乙腈提取、分散固相法净化后用气相色谱仪 ECD 检测。当添加浓度在0.05～1.0 mg/kg 时，各种农药的回收率在63.6%～111.9%之间，相对标准偏差为0.9%～17.6%，最低检测浓度为0.005～0.030 mg/kg。该方法可用于蔬菜中残留农药的快速筛查。
建立瞭分散固相淨化-氣相色譜法同時檢測蔬菜中氟吡菌胺、唑菌酮和茚蟲威等15種殘留農藥的分析方法。樣品經乙腈提取、分散固相法淨化後用氣相色譜儀 ECD 檢測。噹添加濃度在0.05～1.0 mg/kg 時，各種農藥的迴收率在63.6%～111.9%之間，相對標準偏差為0.9%～17.6%，最低檢測濃度為0.005～0.030 mg/kg。該方法可用于蔬菜中殘留農藥的快速篩查。
건립료분산고상정화-기상색보법동시검측소채중불필균알、서균동화인충위등15충잔류농약적분석방법。양품경을정제취、분산고상법정화후용기상색보의 ECD 검측。당첨가농도재0.05～1.0 mg/kg 시，각충농약적회수솔재63.6%～111.9%지간，상대표준편차위0.9%～17.6%，최저검측농도위0.005～0.030 mg/kg。해방법가용우소채중잔류농약적쾌속사사。
Dispersive solid phase cleanup and GC method was developed for simultaneous determining 15 kinds of pesticide residues in vegetable including fluopicolide, famoxadone and indoxacarb, etc. The samples were extracted with acetonitrile, cleaned up by dispersive solid phase, and determined by GC with ECD detector. The recoveries of 15 pesticides were in the range of 63.6%-111.9%, and the relative standard deviations were 0.9%-17.6%at the fortified levels of 0.05-1.0 mg/kg. The limits of quantification were 0.005-0.030 mg/kg.
