摘要: Described is an active check valve that uses electro-magnetic actuation for operation. The valve includes a plunger assembly having a magnet in a sealed internal volume. The plunger assembly further includes a plunger tip that extends from either a plunger assembly housing or a sealing member. Although the plunger assembly is disposed in the solvent flow, the magnet is not exposed to the solvent. When the valve is actuated, the plunger tip moves the sealing member to open or close the valve. Optionally, an arming force may be applied to the sealing member in advance of opening or closing to reduce the subsequent additional force necessary to move the sealing member during opening or closing, thereby improving the accuracy of the solvent composition in liquid chromatography system applications.

摘要: The exemplary embodiments may provide a collective insulating sleeve for a plurality of chromatography columns or may provide separate insulating sleeve for each of the chromatography columns in a plurality. As a result, column ovens are not needed, and pre-heaters may not be required for each chromatography column in some exemplary embodiments. Thus, parallel column arrangements in the exemplary embodiments may be more compact than conventional arrangements.

摘要: A sprayer assembly for an ion source is disclosed. The sprayer includes a capillary having an outlet, a sheath for the capillary, and an elastic member. The sheath can move relative to the capillary between a first position in which the sheath covers the outlet of the capillary and a second position in which the outlet of the capillary is exposed. When the sheath moves from the first position to or towards the second position, the elastic member provides a restoring force that acts to restore the position of the sheath to or towards the first position.

摘要: Described is a chromatographic column assembly that includes an outer tube comprising a metal, a first conduit disposed within the outer tube, a second conduit disposed within the outer tube, and a first joint located between the first conduit and the second conduit. The outer tube is deformed by a first uniform radial crimp at a longitudinal location along the outer tube that surrounds the first conduit on a first side of the first joint, and a second uniform radial cramp at a longitudinal location along the outer tube that surrounds the second conduit on a second side of the first joint. The first and second uniform radial cramps form a fluid-tight seal between the first conduit and the second conduit and each have a substantially flat base region over which a diameter of the outer tube is reduced for a non-zero longitudinal length.

摘要: Systems, methods, and devices for detecting leaks in chromatography systems are disclosed. A coating is disposed to conform to at least one component of a chromatography system, such as a fitting or a section of tubing. The coating is made of or contains a responsive material that can undergo a detectable change when exposed to a chromatographic fluid or mobile phase. The change of the responsive material can indicate the presence of the fluid or mobile phase, a change in at least one physical property of the coating to prevent passage of the fluid or mobile phase, or a combination thereof.

摘要: 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.

摘要: Solvent containers and solvent container trays for chromatography systems are described for providing control over solvent supply and waste collection. Designated solvent containers and exclusively designated solvent containers provide solvents for use by chromatography systems. Control over solvent supply is achieved by requiring matched container shape and container receiving position shape within the tray, and additionally or alternatively, through solvent container coding readable by the solvent tray and chromatography system which provide information about the solvent container to the chromatography system.

摘要: Systems, methods, and devices for detecting leaks in chromatography systems are disclosed. The leak detection system includes a sealable compartment disposed to surround at least one component of a chromatography system. The detector is in communication, e.g., fluid communication, with an interior of the sealable compartment and configured to detect the leak by various mean including the presence of liquid or the presence of vapor, or both within the sealable compartment.
