Puff by Puff Smoking and Individual Puff Analyses / Über zugweises Abrauchen und Pro-Zug-Analysen

Our studies showed that the yield of total phenols per cigarette decreases by 55 % when there is an increase in moisture content. This fact is due to the growth of the filtration constant µ_phenols occurring when the tobacco moisture content rises. The determination of substances contained in the individual puffs revealed a steep increase in the yield of phenols with the puff number, which is caused by the decreasing length of the filtering tobacco rod, by the redistillation of the phenols absorbed in the tobacco rod, and by the increased formation of phenols during the repyrolysis of the condensate
