Abstract: Methods and systems are disclosed for concentrating a compound found in plant material from one or more species of the Cannabis genus. A system includes a capture/heating station having at least one heating element to heat a mass of material held within the capture/heating station; at least one release station in series with and liquidly isolated from the capture/heating station, each release station defining a volume at least partially filed by a release reagent formulated to release a target product from a substrate; and a conveyor configured to carry a belt through the capture/heating station and then the at least one release station.

Abstract: There is described a chromatographic separation member including a substrate carrying on at least one surface a thin layer of a chromatographically active capture material. Also described is a chromatographic separation method for separating a component of interest from a fluid utilizing the chromatographic separation member.

Abstract: There are described processes for the separation of components from a fermentation product or other biomass product. The fluid mixture is passed through a separation column having at least one capture element having flow channels of about 50 &mgr; or greater and which includes chemically active capture material capable of capturing a desired component from the mixture. The separation column may include a plurality of the chemically active capture elements.

Abstract: There are described processes and apparatus for the separation of components from a mixture of components in a fluid such as biological materials in a fermentation broth or other biomass product. The fluid mixture is passed through a plurality of individual separation modules which are in sequential fluid communication, at least one of which can be isolated from the other(s). The individual separation modules include chemically active capture materials which are capable of capturing desired components from the mixture. The chemically active capture material of each individual separation module may have the same chemical activity or the chemically active capture material of at least one separation module may have a different chemical activity than that of the capture material of the other separation module(s).

Abstract: Method of chromatographically separating a mixture by contacting said mixture under chromatographic separation conditions with a chromatographic separation stationary phase comprising a polymer formed by coating substantially all of the surfaces of a microporous, comminuted substrate material with a monomer that is subsequently polymerized in situ with a cold-gas plasma discharge.

Abstract: Method of chromatographically separating a mixture by contacting said mixture under chromatographic separation conditions with a chromatographic separation stationary phase comprising an N-acyl diazepine polymer. In a preferred from, the polymer has been rendered substantially alkali-stable by substitution for the hydrogen at the C3 position on the diazepine ring.
