中文摘要 | 本研究係以具選擇性及靈敏度之高效率液相層析串聯式質譜儀 (LC/MS/MS) 搭配固相萃取 (SPE),建立飼料中林可黴素與觀黴素殘留量之分析方法。使用三段式四極棒質譜儀搭配渦輪噴灑離子源在陽離子模式下偵測林可黴素及觀黴素。林可黴素之方法偵測極限 (MDL) 為0.49 ppb,觀黴素之MDL 為21.23ppb。飼料中添加100 ppb 林可黴素及觀黴素,以本方法測定,其回收率分別為64.80% 及99.68%,CV 值分別為3.67% 及7.10%。本方法可應用於飼料中林可黴素與觀黴素殘留量分析。 |
英文摘要 | The purpose of this study was to develop a specific and sensitive high performance liquid chromatography tandem mass spectrometry (LC/MS/MS) method with solid-phase extraction (SPE) for determination of lincomycin and spectinomycin residues in feed. A triple-quadruple mass spectrometry using a TurboIon Spray source operating in the positive ion mode was used to detect lincomycin and spectinomycin. The method detection limit (MDL) for lincomycin and spectinomycin were 0.49 ng/g and 21.23 ng/g. At 100 ppb level in feed, recoveries of lincomycin and spectinomycin were 64.80 and 99.68 %, with CV were 3.67 and 7.10 %. The method can be applied to analyze the lincomycin and spectinomycin residues in feed. |
