| 目的 研究卷烟商标纸和印刷材料中挥发及半挥发性有机化合物(VOCs和SVOCs)的波动性和一致性的监测及评价方法。方法 利用顶空气相色谱/质谱(HS–GC/MS)采集卷烟包装印刷品及原料中VOCs和SVOCs的色谱图，以氘代苯及氘代萘双内标方法在不同信号采集时间段对分析物保留时间进行校正，依据校正色谱图间相关系数，构建卷烟包装材料中VOCs和SVOCs的质量控制图。结果 该方法操作简单、重现性好，有效校正由于更换色谱柱、仪器开关机及仪器性能波动导致的保留时间偏移，谱图间相关系数最小值由0.407 6提升至0.962 9;该方法能高效地识别不同厂商及不同牌号卷烟商标纸中该类物质的整体差异，差异显著(P＜0.05)，相关系数均值差异率分别为12.5%和38.6%。结论 本研究提供了一种卷烟包装材料中VOCs及SVOCs信号采集、谱图校正和质量控制方法，为卷烟包装材料的质量稳定性评价提供技术手段和支撑方法。 |

| The work aims to study the method for monitoring and evaluating the fluctuation and consistency of volatile and semi-volatile organic compounds (VOCs and SVOCs) in label paper and printing material for cigarette. Headspace-gas chromatography/mass spectrometry (HS-GC/MS) was used to collect the chromatograms of VOCs and SVOCs in package printed matters and raw materials of cigarette. The calibrated chromatograms were obtained after calibrating the retention time at different signal acquisition time periods with double internal standards of benzene-d6 and naphthalene-d8. Based on the calibration chromatograms, the quality control charts were constructed for monitoring and evaluating the fluctuation/consistency of VOCs and SVOCs in packaging material for cigarette. The developed method was simple in operation and good reproducibility. It exhibited good performance in correcting the retention time shift caused by changing the chromatographic column, switching the instrument and other instrument performance fluctuations. The minimum correlation coefficient between the spectra increased from 0.4076 to 0.9629. With this method, the overall differences of such compounds in different manufacturers and packaging papers could be identified efficiently (P<0.05), and the mean difference rates of the correlation coefficients were 12.5% and 38.6%, respectively. This study provided a method for signal acquisition, spectral correction and quality control of VOCs and SVOCs in packaging material for cigarette, which indicated that it could be served as a useful means for evaluating the quality stability of packaging paper and printing material. |
