用毛细管色谱与四极质谱联机检测了苹果中十种国内常用的有机磷杀虫剂。试验结果表明:十种有机磷农药在柱上分离情况较好,保留时间合适。用气质联机对含干扰杂质较多的样品提取液定性比单纯依靠以保留时间为定性依据的气谱法更为准确可靠,其灵敏度也比较高。
By capillary chromatography and quadrupole mass spectrometry on-line detection of apple ten kinds of commonly used organophosphate insecticides. The results showed that ten kinds of organophosphorus pesticides separated well on the column and the retention time was suitable. Qualitative on-line interference with more impurities on the sample extract qualitative than relying solely on the retention time as a qualitative basis of gas chromatography is more accurate and reliable, and its sensitivity is relatively high.
