摘要
A flow through cartridge for solid phase extraction of an analyte from a liquid has a cartridge body bounding a passage for retaining a sorbent. The passage extends from a first end face to a second end face, opposite the first end face of the cartridge body. The cartridge body is composed of a core of a first material extending around the passage and sealing rings of a second material, extending around an axis of the passage at the first and second end faces. Surface portions of the sealing rings constituting surface portions of the first and second end faces. The first material is stronger and stiffer than the second material.
