    摘要: A chromatographic device comprises a tube, a chromatographic medium, a piston assembly, and a locking mechanism. The tube comprises first and second opposite ends and an inner surface. The inner surface of the tube at least in part defines an intermediate region. The intermediate region is generally between the first and second ends. The chromatographic medium is within the intermediate region. The piston assembly is within the tube and is positioned generally between the first end of the tube and the chromatographic medium. The piston assembly defines a passage for flow of process fluid. The piston assembly comprises a piston body portion. The locking mechanism is adjacent the piston assembly and is in engagement with the inner surface of the tube in a manner to prevent movement of the piston assembly relative to the tube axially toward the first end of the tube without preventing movement of the piston assembly relative to the tube axially toward the second end of the tube.

    摘要: A chromatographic device comprises a chromatographic tube, a chromatographic medium, a piston assembly, an elongate rod, and a threaded member. The piston assembly is within the tube and is positioned generally between a first end of the tube and the chromatographic medium. The chromatographic medium is generally between the piston assembly and a second end of the tube. The elongate rod extends partially into the chromatographic tube such that the piston assembly is between the elongate rod and the second end of the chromatographic tube. The elongate rod has a threaded outer surface. The threaded member is threaded to the threaded outer surface of the elongate rod. The treaded member is operatively secured to the chromatographic tube.

    摘要: The present invention relates to a chromatography column that removes the longitudinal load from the column tube altogether and transfers it to a yoke and stanchion arrangement situated around but external to the column tube. By using the yoke/stanchion system, the central adjuster can be used to move the top end into and out of the housing. Thus, when internal pressure is applied to the column, the tube experiences no longitudinal load. Additionally, the yoke and stanchion design allows for complete removal of the end from the tube without cumbersome disassembly. Moreover, the yoke provides a place to retain the end while the tube is being filled, emptied, cleaned or repaired.

    摘要: An apparatus and method for sealing cartridges used in liquid chromatography. Such cartridges are commonly filled with media beds that are bounded axially by porous plates. The invention involves one or two sealing heads. Each sealing head comprises two slidably connected head pieces and an elastomeric sealing member. The head pieces and the elastomeric sealing member are sized to slide easily into an open end of a cartridge when the elastomeric sealing member is uncompressed. After insertion, relative movement of the head pieces compresses the elastomeric sealing member and causes the elastomeric sealing member to expand laterally so that it forms a seal against the cartridge, when the sealing head is pressed against the media bed or porous plate. An alternate sealing head comprises a plurality of head pieces and a plurality of annular elastomeric sealing members. One of the head pieces contains a body portion on which the other head pieces and the sealing members are slidably mounted. The sealing apparatus may employ a sample module that fits within an open end of a column or cartridge. At least one of the sealing members fits within the sample module and creates a seal when compressed.

    摘要: A chromatography column piston 14 is adjustable in height within the column tube 4 by means of a friction clamp 22 which furthermore includes a threaded engagement with the associated end cap 8 of the column. As a result, with the friction clamp released the piston rod 16 can be rapidly traversed to or near a desired position, and the clamp then engaged following which cooperation of said threads allows fine tuning of the level of the piston 14 by fine adjustment of the position of the friction clamp relative to the end cap 8.

    摘要: A syringe type column used for liquid chromatography, wherein a stationary phase (4) and a solvent for development (5) are placed in a cylindrical barrel (1), and an air vent (2a) extends through a plunger (2) which is inserted in the barrel. Development is effected, while the air vent (2a) is closed to prevent air leakage therethrough, by pushing down the plunger (2). When the plunger (2) is drawn out in order to supplement the solvent for development, air flows into the cylindrical barrel (1) through the air vent (2a) so that an inner space of the barrel (1 ) is not held under a negative pressure and the stationary phase (4) is not disturbed.
