摘　　要：本文建立了顶空气相色谱-质谱法同时测定食用植物油中6种溶剂残留的方法。食用植物油加入内标后,在顶空进样器中加热至气液平衡,产生的气体经气相色谱仪分离,进入质谱仪检测。结果表明,目标物质在一定的线性范围内线性关系良好,相关系数均大于0.999;检出限为0.0015~0.1963 mg·kg^(-1),加标回收率为90.06%~102.56%,相对标准偏差在0.42%~2.71%。该方法操作简单、灵敏度高、结果准确可靠,适用于食用植物油中溶剂残留的测定。In this paper,a method for the simultaneous determination of six solvent residues in edible vegetable oil by headspace gas chromatography-tandem mass spectrometry is established.After edible vegetable oil is added to the internal standard,it is heated to gas-liquid equilibrium in a headspace sampler,and the resulting gas is separated by a gas chromatograph and entered the mass spectrometer for detection.The results show that the target substances have a good linear relationship within a certain linear range,the correlation coefficients are all greater than 0.999,the detection limits are 0.0015 mg·kg^(-1) to 0.1963 mg·kg^(-1),the recovery rate is 90.06%to 102.56%,and the relative standard deviation is 0.42%to 2.71%.This method is simple to operate,highly sensitive,accurate and reliable,and is suitable for the determination of solvent residues in edible vegetable oil.
