Smoke Testing - Mainstream - pH
Understand the key constituents of cigarette smoke created once the tobacco is ignited. Mainstream smoke leaves the mouth end of the cigarette after it passes through the tobacco column and filter, and is inhaled by the smoker.
This range of tests provides data for the following constituents of mainstream smoke. Click on each substance tested for further information and interesting facts.
