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.

Embodiments of the present disclosure may assist in managing, storing, using, and re-using dedicated chromatography column bed supports. For example, devices and systems disclosed herein may include reusable cases for storing dedicated column bed supports when the column bed supports are not in use. Such cases may include one or more dividers and inserts configured to fit column bed supports, and may be designed and built specifically to ensure efficient, secure storage of column bed supports while minimizing risk of damaging or contaminating them. Methods disclosed herein may include performing a particular chromatography operation in a column, removing the column bed supports from the column, storing the column bed supports in a column bed support storage case, and installing another set of column bed supports in the column for another chromatography operation.

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.

An integrated system for liquid separation and electrospray ionization includes an emitter-enabled capillary column including an emitter portion and a column portion; and a retractable protective sleeve for covering and/or supporting the emitter portion along at least a portion of its axis. The protective sleeve is mounted around the emitter-enabled capillary column. The retractable protective sleeve is moveable to an extended position wherein a tip of the emitter portion is covered by the protective sleeve. A resilient member is provided to bias the protective sleeve towards the extended position. The protective sleeve is enclosed and moveable within an outer electrically conductive sheath adapted for insertion within a holder having a high-voltage contact point. The sheath is adapted to contact the high-voltage contact point and provide an electrical connection to enable the emitter-enabled capillary column to receive a high voltage. The sheath has a recess to receive the high-voltage contact point.

A column device for an automatic analyser. The automatic analyzer comprises a high performance liquid chromatography (HPLC) module. The HPLC module comprises a fixation device configured to automatically fix and release a chromatographic column. The column device comprises a column jacket and a capillary. The capillary comprises predetermined dimensions and is disposed within the column jacket. The column device is configured to be installed at the HPLC module using the fixation device. Further, an automatic analyzer is disclosed.

The invention provides filters and methods of assembling filters. In an exemplary embodiment, the filter includes a porous element, a compression element, and a housing. The compression element can be configured to receive the porous element, thereby forming an assembly. For example, the compression element can receive the porous element in a slip-fit relationship. The housing can have an opening formed therein that is configured to receive the assembly. In some embodiments, the assembly can be retained within the opening when the assembly is received therein. For example, the opening can receive the assembly in a press-fit relationship.

A column oven comprises: an analysis column including a base end portion positioned on an upstream side in a flow direction of the mobile phase, a tip end portion positioned on a downstream side in the flow direction, and an intermediate portion between the tip end portion and the base end portion; a holding member configured to hold the analysis column; and a heating section configured to heat the analysis column held by the holding member. The holding member includes a base portion and a first sandwiching portion and a second sandwiching portion provided at the base portion to sandwich the intermediate portion of the analysis column and having protruding portions protruding to an opposite side of the analysis column from the base portion in a sandwiching state, and the base portion, the first sandwiching portion, and the second sandwiching portion are integrally formed.

One aspect of the invention provides a gas chromatography union including: a first port; a second port in fluid communication with the first port; and a first pair of wings defining a first recess. Another aspect of the invention provides a union including: a first port; a second port in fluid communication with the first port; and at least a first protrusion defining a first recess. Another aspect of the invention provides a coupler including: a first port; a second port in fluid communication with the first port; and a first connector positioned on a portion of a surface of the coupler.

A gas chromatograph with a positioning system for the inlet liner and the column includes a column and the positioning system for the inlet liner and the column. The column is configured for gas chromatography. Wherein, the positioning system for the inlet liner and the column is configured to position the inlet liner and the column with respect to one another. The positioning system for the inlet liner and the column is configured to repeatably and optimally position the inlet liner and the column with respect to one another.
