摘要： A gradient high pressure syringe pump usable in a high pressure liquid chromatography system includes a housing defining an internal cavity, a drive piston, and a floating piston unconnected from the drive piston dividing the internal cavity into first and second pumping chambers. Each pumping chamber has an intake inlet with an upstream no-return valve communicating with a source of fluid and a discharge outlet communicating with an inlet of a downstream control valve. The control valve is operable to selectively direct fluid from either of the upstream pumping chambers downstream. In one embodiment, the first pumping chamber defines a cylinder section for the drive piston having an internal diameter smaller than the cylinder section defined by the second pumping chamber for the floating piston. The drive piston is moved linearly between suction and discharge strokes by an attached screw operatively coupled with a controllable stepper motor.

摘要： An amphibious vehicle that may be driven directly between land and water includes a vehicle with an opposed pair of flotation side hulls and a rear hull. The side hulls are movable between a stowed position above the vehicle and a lowered deployed position outboard thereof. Each side hull is mounted by arm assemblies including an upright bracket fixed to the vehicle and an arm pivotally connected to the bracket that can be extended or retracted linearly by actuators to raise and lower the side hulls. A locking mechanism prevents the extended side hulls from moving laterally but allows vertical adjustment thereof. The side hulls may be horizontally adjusted between compact contracted and extended protracted positions. The rear hull assembly is pivotally mounted to the back of vehicle permitting raising and lowering thereof and includes jet drives providing propulsion for water operation.

摘要： A container for holding fluids in isolation includes an outer container and two deformable inner containers carried within the internal space of the outer container. The outer container is provided with a view port enabling the user to visually examine the inner containers. The inner containers have respective ports communicating with their interiors. As fluid is withdrawn from the first inner container its volume is reduced so that the second container may receive a like amount of fluid. The second inner container may hold colorants or absorbents. The container may be used with various chemical applications, such as high performance liquid chromatography or fluid injection analysis, wherein supply fluid is withdrawn from the first inner container, used, and returned as waste fluid to the second inner container so that the overall volume of fluids remains relatively constant.

摘要： This modified HPLC instrument has the HPLC pump force only solvent through the serial flow line including a sampler, column, and detector; while buffer is discharged into the solvent from a syringe pump via a tee connection in the flow line downstream from the HPLC pump. A stepper motor drives the syringe pump at a discharge rate to yield an intended buffer/solvent dilution ratio compared to the steady HPLC pump flow rate. A pressure transducer detects variances of the flow line pressures, and servo controls the stepper motor for increasing the flow rate upon increased pressures and decreasing the flow rate upon decreased pressures, to hold the dilution ratio constant.

摘要： This linear drive has cooperating threaded screw and follower components suited to be rotated relative to one another to create a corresponding axial shift between the components, where the follower is improved by having spaced drive members each threadably cooperating with the screw and capable of carrying the maximum axial linear drive force between the components. Anti-friction structures support the drive members for allowing relatively effortless component rotation, frictionwise, even under this maximum driving force. Ramp structures cyclically expand and contract the axial separation between the drive members, which both generates the maximum axial driving force and effectively shifts the axial driving force alternately between the drive members. The force-carrying drive member will be thread friction bound relative to the screw, and the substantially loadfree drive member will be easily rotatable with the follower rotation suited to be axially advanced along the screw. Relative component rotation and repeated expanding and contracting shift cycles incrementally and alternately advance, with an inch-worm like action, the drive members along the screw to provide the axial shift and force generation between the components, the loadfree drive member being advanced and the force-carrying drive member remaining stationary relative to the screw.

摘要： Disclosed is a HPLC system including a first dimension column, a second dimension column, a high pressure switching valve installed along the mobile phase flow path with the usual detector. At a predetermined time after injection of a sample into the mobile phase stream, the valve is actuated so that late eluted components, while still in the first dimension column, are back-flushed to waste by the flow of mobile phase while the analytes get separated in the second dimension column. Mixed-mode cation exchange and anion exchange columns are particularly suited for this application.

摘要： A magnetic reciprocating pump includes a tube having ends defining intake and discharge ports, first and second magnetic plungers axially aligned within the tube of corresponding cross section for reciprocation therewithin, and a plurality of longitudinally spaced coils circumscribing the tube for driving the plungers axially when electrically energized. A gap is defined between the plungers so that the first plunger is slidable between one tube end and the second plunger and the second plunger is slidable between the other tube end and the first plunger. The first plunger closes one port when moved thereagainst and has a peripheral flow path permitting flow when moved away. The second plunger closes the other port when moved thereagainst and has an outer peripheral flow path and a communicating inner axial flow path permitting flow when moved away. The plungers when moved together close the second plunger axial flow path.

摘要： A disposable chromatography sample introduction device includes a stylus with a holder and a tubular stem extending from one end of the holder containing porous sample-holding material. The stylus has a pair of spaced openings permitting fluid flow therethrough. An injector housing includes an insertion port for receiving the stylus, a seal, an inlet port for communicating with one stylus opening, and an outlet port for communicating with the other stylus opening. When the stem is immersed in a sample, sample enters the stem by capillary action. Thereafter, the stylus is inserted into the housing insertion port where mobile phase flowing from inlet port to outlet port passes through the stem extracting sample. The holder has a finger grip and an external thread that engages a complementary injector housing thread to secure the holder when the stylus is inserted therein.

摘要： A pump for use in high pressure liquid chromatography includes a housing with a pump head at one end and an axially-movable, high-pressure piston with a small-diameter plunger reciprocating within the pump head to move fluid from an inlet through an outlet at high pressure. An attached motor rotates a circular cam fixed off center on the motor shaft to reciprocate the piston that has an inner end in engaging contact with the cam periphery. An axially-aligned, torque-compensating piston is provided and has an inner end biased by spring force against the cam opposite the high-pressure piston. A large-diameter piston head may be fixed to the outer end of the torque-compensating piston and slidably mounted within a cylinder defined at the housing end opposite the pump head. The outer end of the piston head is open to ambient atmosphere.
