ABSTRACT:
An integral fitting and filter assembly includes a tubular body (119) having a integral proximal fitting piece (121) and an integral distal fitting piece(122). A central passage (125) extends through the proximal fitting piece and the distal fitting piece of the body. A tubular filter assembly sleeve including a filter sub-assembly (142) and tubular extension sleeve (140) is slidably received within the central passage of the body. The filter sub-assembly includes two end caps (144, 145) and a center piece (146). The center piece is packed with a selective chemical-absorbent packing material (26), that is retained within the center piece by first and second porous plugs (148) secured within opposite ends of the center piece of the end caps. The filter assembly is slidably inserted into the body, and is automatically adjustably positioned longitudinally to provide a pre-column filter that may be used to mate with differently configured mating fittings, such as high-performance liquid chromatography instrument inlet fittings.
