  • Apparatus for fractionation of a standard puff of smoke from a smoking machine
    Patent number: 4204550
    Abstract: A holder for a flat circular filter attached to a smoking machine is provided with a rotatable support for the filter pad. The smoke inlet and suction outlet for the filter holder are offset from the center of the pad and holder and are in matching positions at opposite faces of the pad. At the initiation of each puff, a rotator is synchronized to turn the support and pad through a predetermined arc so that the smoke particulates are spread along said arc of the filter pad. The products of an individual puff are thus positioned for the study of puff fractions. Multiple puffs may be handled on one pad.
