    摘要： A vaporizer apparatus and method for uniformly extracting active ingredients of a specimen of crude natural product or inert particulate matrix impregnated with volatile substances, without pyrolysis, which uses hot air or a heated inert gas stream to volatilize the specimen. The heated air or gas is introduced from below (from either a hot air gun or a high pressure tank connected to a heat exchanger) and ascends through a permeable support structure (e.g., fritted glass disk, etc.), subsequently causing specimen particles disposed on the permeable support structure to be suspended within the confines of an isolation chamber. This allows a maximized gas extraction exposure for each suspended particle, and promotes a uniform extraction of the aggregate charge through its periodic mixing. A filter prevents the particles from being inhaled by the user. During device disuse, the heated airstream flows through an optional side-arm of the vaporizer apparatus, preventing wasteful loss of active ingredients. In another embodiment, the side-arm can also be used to divert mixed purge gases from the specimen required to be under inert gas during its extraction.

    摘要： The present invention is a vaporizer apparatus (1) and method for uniformly extracting active ingredients of specimen of crude natural product, or inert particulate matrix impregnated with volatile substances without pyrolysis which uses hot air (2), or a heated inert gas stream to volatilize the specimen. The heated air or gas in introduced from below (from either a hot air gun or a high-pressure tank connected to a heat exchanger), and ascends through in most embodiments through a permeable support structure (4) (e.g., fritted glass disk, etc.) subsequently causing specimen particules disposed on the permeable support structure to be suspended within the confines of an isolation chamber (5).
