A solid-phase extraction cartridge.

摘要

A solid-phase extraction cartridge 10 comprises a column 12 containing sorbent particles 14 with a porous separation layer 16 above and below said sorbent particles 14 and an end cap 18 above and below said separation layers 16 with an aperature 20 therein permitting liquid to pass through. For eliminating voids between the separation layers and for adapting the cartridge for automatic processes, a cartridge 10 of the above-mentioned type is designed such that the end caps 18 have sealing means 20; 34 adapted to engage and disengage conduits 26, 28; 38 for said liquid and that said end caps 18 are compressible to said column 12. <IMAGE>
