Abstract
A device for the simultaneous determination of main and sidestream smoke in two channels of a Cigarette Components smoking machine is described. It is used to show the whereabout of nicotine of a plain Blend cigarette. Benzopyrene and total phenols of main and sidestream smoke were determined. 10.5 % of the cigarette's total nicotine content were found in the mainstream smoke and 28.2 % in the sidestream smoke. The mainstream smoke contained 1.19 ppm and the sidestream smoke 2.51 ppm benzopyrene, both referred to dry condensate. The total phenol content of the mainstream smoke amounted to 228 µg/cig and that one of the sidestream smoke to 603 µg/cig.
