本发明涉及一种卷烟爆珠中甲醛和乙醛向烟气受热迁移量模拟测定方法，属于卷烟用材料安全性评价技术领域。该方法首先打开热风机，当出风口以及排风口处温度稳定后，将待测爆珠采用醋酸纤维包裹后刺破，之后迅速装入吹扫管中；启动吸烟机进行抽吸，在吸烟机抽吸过程中气流通过吹扫管，把爆珠中能迁移的甲醛和乙醛吹扫出，通过捕集器捕集；吹扫完成后，取下捕集器，从和气流通入相反的方向用极性有机溶剂洗脱捕集器，过滤，滤液采用液相色谱分析，计算迁移率。本发明方法可真实模拟卷烟烟气流对爆珠的洗脱，准确测定爆珠中甲醛和乙醛残留向卷烟烟气迁移量，从而对爆珠中甲醛和乙醛残留安全性进行客观评价。 The invention relates to a method for simulating and measuring the thermal migration quantity of formaldehyde and acetaldehyde in cigarette blasting beads to smoke, and belongs to the technical fieldof safety evaluation of cigarette materials. The method comprises the following steps: firstly, a hot-air blower is turned on, and after the temperatures of an air outlet and an air outlet are stabilized, a to-be-detected blasting bead is wrapped with acetate fibers and punctured, and the blasting bead is quickly put into a purging pipe; a smoking machine is started for smoking, an air flow passesthrough the purging pipe to purge out formaldehyde and acetaldehyde which can migrate in the blasting bead in the smoking process of the smoking
