采用气相色谱法,FID检测器对仓储烟叶中可保特(methoprene)进行分析。其最小检出量为5×10-11g、最小检出浓度为5×10-2mg/kg。气相色谱的响应值与进样量呈正相关。回收率在82.44%～87.91%之间,变异系数在7.01%以下。可保特在仓储烟叶中半衰期为40～79d,80d时的消解率为47.96%～66.61%,残留量均在3.214mg/Kg以下。两年两地试验结果表明,可保特在仓储烟叶中使用,对吸烟者无害。 Gas chromatography and FID detector were used to analyze methoprene in the storage tobacco leaves. The minimum detectable amount of 5 × 10-11g, the minimum detectable concentration of 5 × 10-2mg / kg. The GC response was positively correlated with the injection volume. The recoveries ranged from 82.44% to 87.91%, and the coefficients of variation were below 7.01%. Paul can be stored in the storage of tobacco leaf half-life of 40 ~ 79d, 80d when the digestion rate was 47.96% ~ 66.61%, residues were below 3.214mg / Kg. Two years of trial results show that Paul can be used in storage of tobacco leaves, non-smoker.
