本发明涉及一种卷烟滤棒中凉味剂成分向卷烟烟气迁移的模拟测定方法，属于分析化学技术领域。本发明方法的步骤包括：添加有凉味剂的卷烟滤棒装入吹扫管中，采用本发明装置模拟卷烟真实抽吸对滤棒进行吹扫，用吸附冷阱捕集吹扫出的凉味剂成分，捕集完后通过和动态顶空连接的气相色谱-质谱测定凉味剂成分含量，之后计算迁移率。本发明方法能满足卷烟滤棒中的凉味剂成分向卷烟烟气迁移量准确测定的要求，为卷烟滤棒凉味剂成分的释放和效果客观评估提供了科学、简便的新方法。 The invention relates to a simulated determination method for migration of cooling agent components in a cigarette filter stick to cigarette smoke, and belongs to the technical field of analytical chemistry. The method comprises the following steps of loading the cigarette filter stick added with a cooling agent to a scavenging conduit; scavenging the filter stick by simulating actual smoking of cigarettes by using the device of the invention; trapping the scavenged cooling agent components by using an adsorption cold trap; after trapping, determining the contents of the cooling agent components by using a gas chromatography-mass spectrometry connected with the dynamic headspace; and after that, calculating the migration rate. The method of the invention can meet the requirement for accurate d
