中文摘要 | 本研究昌在建立杭菊中殘留農藥之氣相串聯質譜儀檢測技術,杭菊樣品以乙腈(acetonitrile)進行液-液萃取(liquid-liquid extraction, LLE)及以矽酸鎂固相萃取匣進行固相萃取(solid phase extraction, SPE)後,搭配氣相層析串聯質譜儀(gas chromatography/triple quadrupole mass spectrometer, GC/MS/MS)建立杭菊乾花中112種之多重農藥殘留分析方法。結果顯示,所有農藥皆其有良好的線性關條(R^2≧0.995)。在農藥最低檢測控限(limit of detection, LOD)和最低定量極限(limit of quantitation, LOQ)部分,112種農藥在GC/MS/MS中測定的LOD≦10μg/kg,有79.46%的農藥之LOQ為10μg/kg。在添加高濃度農藥(50和100μg/kg)回收率介於70%-120%分別達77.68%和88.39%'而在添加低濃度農藥(10和20μg/kg)下,則不到10%的農藥達到此標準。顯示本研究所建立之分析方法,可應用於國內外杭菊產銷之監測檢驗。 |
英文摘要 | In this study, the 112 multiple pesticide residues in Chrysanthemum morifolium were extracted by LLE with acetonitrile as the solvent followed by sample clean-up by SPE using florisil cartridges, and the extracts were analyzed by GC/MS/MS. The present results showed good linearity by correlation coefficients of more than 0.995 for all analyses. The LOD of all analyses were less or equal to 10 μg/kg. The LOQ were 10 μg/kg for approximately 79.46% of pesticides. The attained recoveries were typically between 70% and 120% with the RSD values typically lower than 20% were 77.68% and 88.39% of pesticides at spiking levels of 50 and 100μg/kg. Then, at spiking levels of 10 and 20μg/kg, there were below 10% of pesticides reaching the standard. The results demonstrated that the GC/MS/MS method was successfully utilized to determine the trace level amounts of pesticides residues in Chrysanthemum flowers samples. |
