    摘要: A chromatography column cartridge system comprised of an internal pressure-stable precision glass tube which can be filled with adsorbent and an external protection and/or temperature control jacket with column connection parts which can be screwed on. The column connection parts comprise a union nut which is screwed onto the protection and/or temperature control jacket. The union nut contains a milled nut and a plunger which seals the glass tube radially. Feed and discharge lines for the mobile phase pass through the column connection parts.
