Abstract: A vapor sample collection apparatus and method of vapor sample collection. The vapor sample collection apparatus has a connection port to connect a first end of a tube to an exhaust port of a vaporizer device, a vacuum pump connected to a second end of the tube, a manifold connected to the vacuum pump, and a vapor containment vessel for collecting a vapor sample, where the vacuum pump is configured to draw a predetermined pressure on the tube. The method of vapor sample collection includes connecting a connection port to an exhaust port of a vaporizer device, the connection port being attached to a first end of a tube, activating the vaporizer device to vaporize a sample containing an active ingredient, drawing a predetermined pressure on a second end of the tube using a vacuum pump, and collecting a vapor sample from the vaporizer device in a vapor containment vessel.

Abstract: A vaporizer device is described in which a first air pathway extends from an inlet to a heating element. The heating element is configured to heat air from the first air pathway to produce heated air. A second air pathway extends from the heating element to a mouthpiece and is configured to carry the heated air. The first air pathway is configured to bring the air into thermal contact with at least one component in the second air pathway which absorbs heat from the heated air to heat air in the first air pathway and thereby reduce the energy needed to heat the air.
