AbstractA method was developed to measure the amount of an SV smoke component captured by a filter for at least the duration of a puff and eluted from the filter by subsequent puffs of cigarette smoke. It was concluded that the size of the filament affects the elution of nicotine by a cellulose acetate filter and that the elution phenomenon is an important factor in the filtration mechanism of nicotine and a minor factor in the filtration mechanism of TPM. Due to condensation, there is a
