A horizontal axis rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. The process physically separates resin rich beads at the trichome gland head from extraneous plant matter by one or move separation sieves. The sieves are provided in or as a casing over a rigid frame member. The sieves are mesh fabric bags or screen that are easily opened and replenished in a batch operating mode, and are removable from the frame for cleaning and maintenance. Other aspects of the invention include processes that improve process efficiency and speed, and yield products of superior quality.

Methods, apparatus, and systems for provision of an aerosol/vapor trap for elemental impurities emission analysis of high viscosity matrices used in non-burning vaporization devices are disclosed. In an embodiment, filter material filter material captures one or more elemental impurities from a non-burning vaporization device. A vessel contains the filter material. Other embodiments are also disclosed and claimed.

A filter assembly comprising: an inner cartridge; an outer cartridge; a cartridge flange end cap comprising a base peripheral flange and centrally-located cylindrical raised base; a cartridge flange top cap comprising a ring portion defining an opening, a peripheral flange; whereby one end of the inner cartridge is held around the centrally-located cylindrical raised base and other end of the inner cartridge is received by the opening in the cartridge flange top cap; and one end of the outer cartridge engages an inner wall of the base peripheral flange and other end of the outer cartridge engages an inner wall of the peripheral flange.

A filter includes a filter outer wall, and a filter inner wall spaced apart from the filter outer wall. The filter inner wall and the filter outer wall define a filter void therebetween, and the filter inner wall and the filter outer wall extend along a filter axis. A volume of filtration material is positioned in the filter void, and a plurality of baffles extend between the filter inner wall and the filter outer wall. The plurality of baffles are configured to induce a helical component to an airflow entering the filter void at a first void end relative to the filter axis and exiting the filter void at a second void end opposite the first void end.
