[目的]提出吹扫捕集-气相色谱测定粮食中多种熏蒸剂的分析方法。[方法]该方法借鉴了EPA方法5035,在粮食中添加1.0～40.0μg/kg质量分数范围的加标试验。[结果]熏蒸剂在0.09～48.0μg/kg时具有良好的线性关系,相关系数r=0.9996。不同熏蒸剂检出限为0.4～1.5μg/kg(S/N≥4),平均回收率为84.0%～92.7%,相对标准偏差(n=6)为1.5%～8.7%。[结论]方法简单、高效、灵敏、成本低。 [Objective] The purifying and trapping-gas chromatography was developed for the determination of various fumigants in food. [Method] This method borrowed EPA method 5035 and added spike test in the range of 1.0 ~ 40.0 μg / kg mass fraction. [Result] The fumigant had a good linear relationship at 0.09 ~ 48.0μg / kg, the correlation coefficient was 0.9996. The detection limits of different fumigants were 0.4-1.5μg / kg (S / N≥4). The average recoveries ranged from 84.0% to 92.7%. The relative standard deviations (n ​​= 6) ranged from 1.5% to 8.7%. [Conclusion] The method is simple, efficient, sensitive and low cost.
