摘　　要：报道了利用同步辐射真空紫外单光子电离飞行时间质谱技术实时分析卷烟烟气的新方法,及其对两种不同类型卷烟主流烟气气相成分进行分析研究所取得的一些实验结果。首先,采用自行设计的注射器对卷烟烟气进行采样,初步研究了陈化时间对烟气化学成分的影响,并通过扫描光电离效率谱(PIE)曲线获得了一些不同质量数的烟气组分的电离能;然后,利用改造后的单通道吸烟机在国际标准条件下抽吸卷烟,探讨了某些单口烟气成分随抽吸口数的变化情况。结果表明,虽然陈化时间对卷烟烟气气相成分有较为明显的影响,但是通过PIE的测量能够较好地对烟气组分进行定性分析;另外,采用商用吸烟机与同步辐射光电离质谱相结合能够实现无需对样品进行前处理的条件下,在秒量级时间内对单口烟气进行分析。A new method using synchrotron radiation vacuum ultraviolet （VUV） single-photon ionization time-of-flight mass spectrometry for real-time analysis of cigarette smoke was developed by utilizing a home-made sampling device for collecting mainstream smoke and a modified Borgwaldt single-port smoking machine. Results showed that qualitative analysis of multiple components of tobacco smoke can be well accomplished by scanning photoionization efficiency spectra （PIE）, although there were aging effects. In addition, commercial smoking machine combined with synchrotron radiation VUV photoionization mass spectrometry can realize puff-by-puff analysis of cigarette smoke without ore-treatment within a few seconds.
