Analysis Apparatus Column Oven
Implemented is an analysis apparatus column oven equipped with a plurality of columns, which is capable of efficiently performing heat conduction on column basis, recognizing a column cartridge that holds a column, and being easily exchanged on column basis. The column change mechanism 105 includes the ferrule 206, the movable ferrule connector 207, the pipe 208, the fastener pull 209, the fastener fitting 210, the column cartridge presser 211, the slide guide 212, the RFID reader 214, the fixed wall 215, the column changer heat insulating member 216, the fixed bottom plate 217, the receiver 218, and the fixed fitting 219. A plurality of column cartridges 104 can be installed in the heat block 101, and are in contact with the column heat block 103 to control the temperature in the column cartridges 104. The column cartridge 104 is fixed between left and right column change mechanisms 105, and when the fixed column cartridge 104 is opened, the column change mechanism 105 on the left side is moved leftward and opened.
Pre-assembled separation columns
There is provided an integrated system for liquid separation, such as LC, CE, affinity chromatography, and ion exchange chromatography, comprising a column and end-fittings embedded in a plastic material, such as a thermoplastic polymer. The system may further comprise an electrospray emitter directly connected with the outlet of the column, wherein a substantial part of the emitter is covered with the polymer material. There is also provided a method by which a separation column along with the accompanying end fittings for connection with adjacent liquid conduits is embedded in a polymer matrix. This configuration e.g. ensures that the factory-made, correct attachment of the fittings to the column is preserved (since the matrix prevents further user intervention, accidental or otherwise). Accordingly, the responsibility for the correct attachment of the fittings is shifted from the end user to the manufacturer.
CHROMATOGRAPHY COLUMN POSITIONING ASSEMBLIES
The exemplary embodiments provide chromatography column positioning assemblies that can ensure that the distance between face seals or other sealing surfaces/mechanisms at the respective ends of a liquid chromatography column is a desired distance (i.e., the length of the liquid chromatography column). The exemplary embodiments can adjust the separation between the face seals to accommodate different length liquid chromatography columns. For example, a chromatography column positioning assembly of an exemplary embodiment can set the distance between face seals to accommodate a 25 mm column, a 50 mm column or a 100 mm column.
Fluid supply device for fluid chromatograph
A fluid supply device for a fluid chromatograph includes a storage container, a pump device, a filter, a guide and a heat dissipation device. The pump device supplies a mobile phase to a column. The storage container stores the pump device and the filter and has an intake port. The guide guides gas that has been introduced into the storage container through the intake port to the filter. A heat dissipation device dissipates heat generated from the pump device to the outside of the storage container together with the gas inside of the storage container. The storage container includes a door having a front surface directed forwardly of the fluid supply device. The intake port is provided at the door to be directed sidewardly of the fluid supply device.
Column attaching method and heating device
When a column is attached to an attachment location, first, a ferrule through which the column is inserted is heated and thus is fixed to the column. Then, the column to which the ferrule is fixed is attached to the attachment location. As described, when a user performs work of attaching the column to the attachment location, the ferrule is always fixed to a certain spot of the column. Therefore, it is possible to omit work of holding the ferrule such that the position of the ferrule with respect to the column does not shift when the work of attaching the column is performed. As a result, the column can be easily attached to the attachment location.
Stackable planar adsorptive devices
Adsorptive bed devices include a monolithic scaffold having a stress absorbing rigid structure and open cells filled with adsorptive beads. The monolithic scaffold restricts movement of the plurality of adsorptive beads, absorbs stress induced by a hydraulic pressure gradient along a direction of liquid flow. In one embodiment the adsorptive bed is packed into a chromatography column, and in another embodiment the adsorptive bed is sealed in a monolithic block. In another embodiment, the adsorptive bed device includes an adsorptive block, first and second planar distributors and peripheral seal.
FITTING ASSEMBLIES FOR FLUIDIC CONNECTIONS
A fitting assembly (100) is provided. The fitting assembly (100) comprises a holder (102) that holds one or more fluidic seal assemblies. The fluidic seal assembly comprises a fitting (104), a ferrule (110) and a tube (112), such as a chromatography column, and optionally comprises a protrusion (118) and a compliant seal material (120). Fluidic connections for a gas chromatography instrument are also provided.
CAPILLARY ARRAY UNIT
Provided is a capillary array unit configured to facilitate attaching/detaching operation. A capillary array unit includes a capillary, a load header provided at one end of the capillary, a capillary head provided at the other end of the capillary, a detection section provided at a portion of the capillary, and a holder holding the capillary. The holder includes a first holding section holding the capillary in a curved shape, a second holding section linearly holding the capillary, and a guide to move the second holding section in a predetermined direction.
ESTABLISHING FLUIDIC CONNECTIONS BETWEEN CHROMATOGRAPHY COMPONENTS
A clamp assembly includes a rail extending along the length and configured to receive a first fluidic assembly, and a carriage movably attachable to the rail such that the carriage moves along the rail, the carriage configured to receive a second fluidic assembly, the carriage including an actuator and a stop mechanism. The stop mechanism is configured to selectively prevent and allow movement of the carriage relative to the rail. The stop mechanism is configured to be independently operable from the actuator assembly, and the actuator is configured: to move a chromatography column received by the clamp assembly relative to the rail to create a first fluid tight seal between the chromatography column and the first fluidic assembly, and move the second fluidic assembly relative to the carriage body to create a second fluid tight seal between the second fluidic assembly and the chromatography column.
Chromatography and synthesis column apparatus and method of assembly
Chromatography and synthesis columns, assemblies, components, and methods of assembly and disassembly are disclosed including a support assembly having lifting mechanisms in each of the legs to raise and lower a frame secured to the column, a swing arm and/or carriage guiding movement of a bottom plate of the column, a bolt-free coupling between the main tube and bottom plate of the column, and upper and lower slurry ports in the main tube of the column.
