Solid filter used in cartridges for solid phase extraction systems for treating water samples contains cellulose fibers, paper fibers, wood pulp fibers, plastic fibers and/or glass fibers

摘要

Solid filter containing cellulose fibers, paper fibers, wood pulp fibers, plastic fibers and/or glass fibers, is new. Preferred Features: The fibers are housed in a flexible material so that water can penetrate the housing without the fibers leaving the housing. The fibers are fixed in position in a cartridge. A barrier which is water-permeable but impermeable for the fiber material is fixed in the inlet and outlet sides.
