Characterization of mainstream cigarette smoke aerosol by size-fractionated chemical analysis of nicotine, solanesol, and tobacco-specific nitrosamines

Figures & data

Table 1. Parameters of cigarette samples.

Parameter	3R4F	Hongtashan	Dunhill
Filter ventilation (%)	39.7	37.7	55.3
Pressure drop ΔP (Pa)	1626	1229	1576
ISO NFDPM (mg)^a	9.4	7.0	4.0
Nicotine (mg)	0.65	0.7	0.4

^a NFDPM: nicotine-free dry particulate matter; measured under ISO smoking conditions (puff volume, 35 mL; puff duration, 2 s; puff interval, 60 s) (ISO2012).

All cigarettes were conditioned at 22 ± 1 °C and 60 ± 3% relative humidity for more than 48 h before analyses.
