Abstract:
1. Assembly of a cartridge and a cartridge clamp, said cartridge having a cartridge body bounding a passage for retaining a sorbent, said passage extending from a first end face of the cartridge body to a second end face of the cartridge body, opposite the first end face of the cartridge body, said cartridge clamp having a first clamping jaw comprising a first clamping face and a second clamping jaw comprising a second clamping face, said first and second clamping faces being opposite of each other and facing each other, at least one clamping jaw being mounted to a slide movable along guides towards and away from the other clamping jaw, respectively, a first conduit being connected to the first clamping jaw and a second conduit being connected to the second clamping jaw, said conduits extending through the respective clamping jaw and each having an end aperture in the clamping face of the respective clamping jaw, said cartridge clamp being adapted for clamping said cartridge in-between the first and the second clamping face and for forming a closed circuit composed of the first conduit, the passage and the second conduit during clamping, each clamping face having a ring-shaped protrusion extending around the end aperture of the respective conduit, said protrusions being arranged for each contacting and deforming the end faces of the cartridge body when the cartridge is clamped between the clamping jaws with the passage of the cartridge aligned with the apertures in the clamping faces, wherein the cartridge body is completely made of PEEK or of a single material having a density, a Young's-modulus, a tensile strength, a water absorption, a thermal degradation and a chemical resistance substantially similar to PEEK, and in that each ring-shaped protrusion has a contact end face for contacting a contact surface of the end face of the cartridge body, said contact end face comprising a flat surface part, said flat surface part being parallel to the end face of the cartridge body during clamping for creating a positive mechanical engagement between the clamping face and the respective contact surface of said respective end face of the cartridge body during clamping of the cartridge between the clamping jaws.
