Cigarette base paper parameters like permeability and burn additives have a large impact on mainstream smoke yields of cigarettes. Especially CO and potentially also CO2 and O2 yields could change by applying LIP/FSC-bands on cigarette papers. Other analytes will show similar trends. Physical band parameters like permeability, diffusivity as well as the band design have an influence on those smoke yields. The sample set involved cigarettes with permeabilities in a range of 50-130 CU and burn additive levels between 1-2%. Cigarettes have been produced with base papers containing bands with different diffusivities and band designs. The sample cigarettes were smoked according to ISO 3308, with fully blocked filter ventilation. Changes in mainstream smoke yields of CO, CO2 and O2 and other analytes will be presented. A single channel smoking machine (Borgwaldt RM1) and a mass analyzer (Airsense Compact) were used for the determination of mainstream smoke yields. A specially designed interface was applied to split a fraction of the mainstream smoke. The smoking machine triggered the interface in such a way that smoke can only enter the mass analyzer during a puff. Electron impact ionization was used for detecting CO2 and O2 whereas CO and other analytes were determined by ion molecule reaction ionization. This study compares smoke yields of non-LIP/FSC and LIP/FSC cigarettes with different base paper parameters (e.g. permeability, burn additives), different band diffusivities and different band designs. To determine further differences between non-LIP/FSC and LIP/FSC cigarettes puff-by-puff analysis have been carried out. Further smoke constituents have been measured by smoking cigarettes through desorption tubes and were analyzed by GC-MS afterwards. A puff-by-puff smoking regime served to determine the differences between a puff smoked on a band area and a puff taken on the band spacing.
