Chromatography detector
A chromatography detector comprises: a flow cell with a flow path where the sample and a solution flow, the flow cell including outlet tubing that discharges the sample and the solution from the flow path; a connecting member configured to connect the outlet tubing of the flow cell and external tubing outside the flow cell; a wall member including a through-hole; a securing member configured to secure the connecting member to the wall member; and a tray below the securing member. The securing member includes a holder configured to hold the connecting member, an attachment configured to be inserted through the through-hole of the wall member, and a fluid guide formed in such a manner as to, upon the solution leaking out of the connecting member, guide the leaked solution to the tray.

Column device for liquid chromatography and liquid chromatography apparatus
A cylindrical column body (101) holds a filler. A pair of end caps (105, 106) covers both ends of the column body (101) and has a flow hole for a carrier liquid (111, 112) arranged in the center thereof. An end surface on the side of a large diameter portion (113a, 114a) of a pair of columnar joint members (113, 114) contacts an end surface of the pair of end caps (105, 106) and also has a communication hole (115, 116) arranged in the center thereof. A sealing member (117, 118) is arranged on a contact surface between the end cap (105, 106) and the joint member (113, 114). A bottomed cylindrical case (121) accommodates the pair of end caps (105, 106) and a large diameter portion of the pair of joint members (113, 114) in an engaged state. A cover member (124) is detachably installed on a side of an opening of the case (121).
Chromatography column support
Herein is reported the use of a chromatography column support comprising at least one plane of symmetry, one axis of symmetry, at least three legs, at least three straight connectors, whereby the connectors define a plane that is perpendicular to the axis of symmetry of the support, whereby the connectors are connected to each other at the axis of symmetry, whereby each leg is connected to a connector, whereby each leg is perpendicular to the plane defined by the connectors, whereby all legs are on the same side of the plane defined by the connectors for stabilizing the packing of a chromatography column.
Establishing fluidic connections between chromatography components
A clamp assembly includes a rail configured to receive a first fluidic assembly, and a carriage slidably mounted to the rail and configured to receive a second fluidic assembly. The carriage is operable to establish a first fluid tight seal between the first fluidic assembly and a chromatography column received within the claim assembly, and to establish a second fluid tight seal between the second fluidic assembly and the chromatography column.
FLOW-FIELD-INDUCTED TEMPERATURE GRADIENT GAS CHORMATOGRAPHY
The invention relates to a method, to a device, and to the use of a method for the gas-chromatic separation and determination of volatile substances in a carrier gas by means of a chromatographic separating capillary (1), wherein the separating capillary and/or an enveloping capillary (2) surrounding the separating capillary (1) is electrically conductive and is heated with current in the form of a resistance heater and is cooled by a forced convective flow by means of a fluid in the form of a gradient flow field in such a way that a continuous temperature gradient arises over the length of the separating capillary.
CLAMPING DEVICE FOR A SAMPLE PREPARATION
The clamping device according to the invention for clamping at least two processing devices for a sample preparation is made up essentially of at least three clamping blocks arranged in the axial direction, at least two of which are designed as movable clamping blocks, and a displacement mechanism for displacing the movable clamping blocks between an open position for inserting the processing devices, and a clamping position in which the at least two processing devices are clamped one on top of the other in the axial direction between two clamping blocks in each case. The displacement mechanism is designed for displacing the at least two movable clamping blocks in opposite directions.

MOUNTING A SAMPLE SEPARATION UNIT BY A SWIVEL MECHANISM
A mounting device for mounting a sample separation unit configured for separating, preferably chromatographically separating, compounds in a fluidic sample includes a first fluid connector configured for being mechanically and fluidically coupled with a first fluid interface of the sample separation unit, a second fluid connector configured for being mechanically and fluidically coupled with a second fluid interface of the sample separation unit, and a swivel mechanism configured for swivelling the first fluid connector between a mounting orientation for mounting the first fluid interface of the sample separation unit at the first fluid connector and an alignment orientation for aligning the second fluid interface of the mounted sample separation unit with the second fluid connector for subsequently coupling the second fluid interface with the second fluid connector.
Chromatographic cassette
A chromatographic cassette includes a cassette including a chamber, chromatographic media disposed within the cassette chamber, a distribution network fluidly coupled to the chromatographic media and an inlet port and an outlet port coupled to the distribution network. A hyper-productive chromatography technique includes providing a scalable and stackable chromatographic cassette, loading a sample to be processed, operating the scalable chromatographic cassette having an adsorptive chromatographic bed having a volume greater than 0.5 liter by establishing a flow at a linear velocity greater than 500 cm/hr with a residence time of the loading step of less than one minute.
