Determination of mainstream cigarette smoke pH value based on Impinger 5 box trapping method
摘要
Abstract
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 meas-urement 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 sam-ples 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.关键词
