Determination of Particulate Matter and Carbon Oxides in Sidestream Smoke

An investigation was performed to determine optimum conditions for the generation and collection of particulate matter and carbon oxides in sidestream smoke with a cylindrical chamber of 80 mm internal diameter. The most adequate conditions were found to be 50 cm distance between the burning cone and the Cambridge filter pad and 10 l/ min air flow rate through the chamber. Under these conditions, the static burn rate was virtually the same as that without the chamber and almost constant values for condensate were obtained by replicate measurements. Furthermore, the concentration of carbon monoxide delivered to a room could be estimated by this method. But, it was not possible to estimate the concentration of smoke particles in a room by use of sidestream measurements.
