One-Dimensional Gas Concentration Profiles Within a Burning Cigarette During a Puff

A technique for axial concentration measurements of several gas phase components of cigarette smoke during a two-second puff has been described. Gas concentration profiles constructed from these measurements were used to determine the axial order of the reactions which determine these concentrations. A one-dimensional model combustion reaction profile and a one-dimensional model coal temperature profile were presented. The diffusivities of several combustion gases through cigarette paper were calculated from the concentration data using the Owens-Reynolds model for the isothermal diffusion of gases through cigarette paper.
