Abstract
An apparatus for collecting samples of smoke components from predetermined segments of drawn smoke during a predetermined time interval is disclosed. The apparatus includes a smoking machine for drawing successive individual puffs of smoke from a cigarette and for providing a predetermined path of travel for drawn smoke. The particulate matter of the drawn smoke is collected on a filter pad positioned on a movable stage for providing relative movement between the filter pad and the path of travel of the drawn smoke. Advantageously, the filter pad is moved transversely relative to the path of travel of the drawn smoke. A method for collecting samples of smoke components of drawn smoke is also provided.
