摘　　要：为提高卷烟主流烟气pH值的测定精密度，提出了一种基于Impinger5box捕集方式同时收集烟气粒相物和气相物的主流烟气pH值测定方法，并对测定条件进行了优化．最优测定条件为抽吸烟支数10支，萃取剂体积90mL，振荡时间30min．在该条件下对5种不同牌号卷烟样品进行验证试验，结果表明，RSD在0．302％～0．562％之间，主流烟气pH值的平均差值≥0．030的样品之间表现出了显著差异性．该方法可在不改变吸烟机抽吸参数的情况下进行卷烟抽吸和烟气捕集，测定方法简单、方便，测定结果精密度较高，重复性较好．In order to improve the measurement results precision of cigarette mainstream smoke pH, a method which based on Impinger 5 box trapping method of the pH value of particulate matter and vapor phase matter of cigarette mainstream smoke was established, and the measurement conditions were optimized. The best measurement conditions were： the cigarette number was 10,extraction solvent volume was 90 mL and the shaking extraction time was 30 min. Under the condition, the pH value of 5 different kinds verification of cigarette samples was tested with the method and the result indicated that the RSD of the method was 0. 302% - 0.562%, the average difference of the mainstream smoke pH value which was greater than or equal to 0. 030 showed a significant difference. This method could be used without changing the smoking machine pumping parameters and it was simple, convenient and the determination results had high precision and better repeatability.
