Abstract

Particle size distribution of cigarette side-stream smoke (CSSS) was measured just above the burning tip with a laser light scattering method. 2-D polarization-sensitive laser light scattering (2DPLLS) system was applied to the in situ measurement of CSSS since this method can acquire the spatial distribution of particle mean diameter with ICCD camera. It was found that the particle mean diameter was 0.33 μm with the geometric standard deviation of 1.3, in favorable comparison to the particle mean diameter of 0.24 μm with the geometric standard deviation of 1.1 at 2 mm above the burning tip, which was measured by 1-D multi-angle laser light scattering (1DLLS) method. Furthermore, we measured the entire particle size distribution using a scanning mobility particle sizer (SMPS) and obtained the particle mean diameter of 0.17 μm with the geometric standard deviation of 1.5. The values obtained in the present work were reasonably in good agreement with those reported by other researchers using ex situ methods. Consequently, we concluded that the in situ 2DPLLS method is suitable for the measurement of CSSS.
