中文摘要 | 本研究參考歐盟2009年公告QuEChERS萃取方法(DIN EN 15662),利用液相層析串聯質譜儀(LiquidChromatograph/Tandem Mass Spectrometer)進行偵測,以建立Penflufen於糙米中殘留分析方法。糙米基質添加標準品 (0.01-0.05 μg/g)平均回收率介於80.0-92.0%,變異係數介於0.8-5.3%。定量極限(Limit ofquantification, LOQ)為0.01 μg/g。本研究利用QuEChERS殘留萃取操作簡易,及LC/MS/MS分析靈敏度之優勢,方法確效結果之準確度及精確度均佳,可應用於稻米中Penflefen殘留檢測。 |
英文摘要 | A sensitive and selective analytical method for the determination of penflufen residue in brown rice was developed. Residue of penflufen in matrices was extracted by QuEChERS methodology. Quantification was performed by reversed phase HPLC with electrospray MS/MS-detection. The overall recoveries for penflufen from rice were between 80.0 and 92.0% with a relative standard deviation between 0.8 and 5.3%. The detector linearity and the repeatability of the method proved to be very precise. The limit of quantification (LOQ) was 0.01 μg/g for penfluen in brown rice. These validation results demonstrate the excellent sensitivity, accuracy and precision of the method, which can be applied to detect penflufen residue in rice. |
