| 目的 建立同时测定食品烘焙用纸包装中9种有机溶剂残留量(丁酮、苯、甲苯、对二甲苯、间二甲苯、邻二甲苯、乙酸乙酯、乙酸丁脂、正丁醇)的方法。方法 通过优化自动顶空(HS)-气相色谱(GC)-串联三重四级杆质谱(MS/MS)仪器的自动顶空进样器、色谱、质谱检测。采用优化条件，样品平衡温度为120 ℃，顶空平衡时间为30 min，用Thermo TG-WAXMS色谱柱分离化合物，进样分流比为25∶1，采用外标法定量，MRM(多反应监测模式)模式GC-MS/MS方式检测食品烘焙用纸。 结果 采用该方法能完全分离9种有机溶剂，且线性良好(相关系数在0.99以上)，方法检出限为0.003～0.010 mg/m2，回收率为93.8%～101.5%，RSD范围为1.3%～3.5%。结论 该方法与气相色谱检验方法比较，更简单快捷，分离效果好，结果准确，检出限更低，可用于实际检测大批量食品烘焙用纸包装产品中9种有机溶剂残留量。 |

| The work aims to set up a method that can determine 9 kinds of organic solvent residues in food baking paper packaging (butyl ketone, benzene, toluene, terephthalic acid, isophthalic acid, phthalic acid, ethyl acetate, butyl acetate ester, n-butyl alcohol). The headspace sample injector, chromatography and mass spectrometry of automatic headspace (HS)-gas chromatography (GC)-series triple level 4 pole mass spectrometry (MS/MS) were optimized for determination. The optimized conditions were as follows:the sample equilibrium temperature was 120 ℃, the headspace equilibrium time was 30 min, the compounds were separated by Thermo TG-WAXMS chromatographic column, and the injection flow ratio was 25∶1. The quantification was carried out by external standard method and the determination was conducted by GC-MS/MS of MRM mode. 9 kinds of organic solvents could be completely separated, with good linear correlation coefficients of above 0.99, method detection limit between 0.003 ~ 0.010 mg/m2, recovery rate between 93.8% ~ 101.5% and RSD between 1.3% ~ 3.5%. The method is easier and faster compared with gas chromatography, with good separation effect, accurate result and lower detection limit and can be used to actually determine 9 kinds of organic solvent residues in paper packaging products. |
