Cigarettes. Determination of ammonia in cigarette mainstream smoke with an intense smoking regime using ion chromatography 香烟离子色谱法测定浓烟环境下卷烟主流烟气中的氨

发布日期： 2020-07-03

BS ISO 23920:2020规定了使用ISO 20778吸烟参数通过离子色谱法对主流烟雾中的氨进行定量的方法。该方法适用于约10 g/支到40 g/支的氨产量。本法不适用于测定深色空气固化香烟中的氨。

BS ISO 23920:2020 specifies a method for the quantification of ammonia by ion chromatography in mainstream smoke using ISO 20778 smoking parameters.This method is applicable to an ammonia yield of about 10 g/cigarette to 40 g/cigarette. It is not applicable for the determination of ammonia in dark-air cured cigarettes.
