As presented at the CORESTA Congress 2012 a puff-by-puff profile of LIP cigarettes shows differences in CO and O₂ between a puff taken on the banded area and a puff on the band spacing. The cigarettes for the investigation of CO and O₂ have been smoked according to ISO 3308 with a puff volume of 35 ml.

In continuation of the study presented in 2012 effects were studied for larger puff volumes. Cigarettes have been produced with different base paper parameters and bands with different diffusion capacities. Cigarette papers with permeabilities in a range of 50-125 CU and burn additive levels between 1-2% have been used for the investigation of the base paper parameters and band diffusion capacities vary between 0.05-0.15 cm/s. A puff-by-puff profile of the sample cigarettes with fully blocked filter ventilation was taken by simulating the puff volume of 55 ml of the Canadian Intense smoking regime. Changes in mainstream smoke yields of CO, O₂, tar and nicotine will be presented.

A single channel smoking machine (Borgwaldt RM1), a mass analyser (Airsense Compact), a GC-FID and GC-TCD were used for the determination of mainstream smoke yields.

This study compares smoke yields of non-LIP and LIP cigarettes with different base paper parameters (e.g. permeability, burn additives) and different band diffusion capacities.
