摘要: Sample preparation and separation can be performed using a sample cartridge (201). The cartridge includes a barrel (204) with a first and second end, a column segment (209) connected to the second end of the barrel, and a column (205) containing a sorbent material. The sorbent material includes particles that have antibodies attached to them to selectively retain analytes, proteins attached to them to retain certain classes of antibodies, or enzymes attached to them to perform specific modifications to certain classes of molecules. The column segment can be in thermal communication with a temperature control device in order to control the temperature of the column.

摘要: A solvent delivery subsystem for a chromatography device performs relatively low pressure, high flow mixing of solvents to form a gradient and subsequent high pressure, low flow delivery of the gradient to the separation column. The mixing of the gradient is independent and does not interfere with the gradient delivery. To form the gradient, the outputs of an aqueous pump and an organic pump are mixed to fill a storage capillary while a downstream point from the storage capillary is vented to atmosphere. After gradient formation, the vent to atmosphere is closed, the solvent delivery system rises to high pressure, and only the aqueous pump runs for gradient delivery. To maintain integrity of the fluid stream, the solvent delivery system uses feed forward compensation and controls at least one parameter selected from the group consisting of pressure and flow in the conduit means to follow a gradual ramp.

摘要: Methods for transferring a carbon dioxide based separation procedure from a reference chromatographic system to a target chromatographic system involve alternative techniques for determining system pressure drops not attributable to the column. One technique involves leveraging experimental chromatography to develop a correction factor that is a function of at least one correction coefficient and at least one ratio of the differential analyte retention time to the retention time in the reference system. Another technique involves leveraging other experimental measurements of tubing pressure drops under various condition to develop a lookup table that can be used to identify likely tubing pressure drops in the target system. A third technique leverages knowledge of the separation procedure and the target system and the likely nature of the relevant flow to calculate tubing pressure drops in the target system.

摘要: A check valve includes a first valve body having a chamber in which second and third valve bodies are located. The check valve also includes a spring-energized seal disposed in the chamber. The spring-energized seal includes a compliant seal body having an annular shape and a resilient member, such as a cantered spring or O-ring, disposed in a pocket of the seal body. The resilient member applies a force to portions of the seal body to prevent the passage of fluid from a valve inlet port to a valve outlet port unless the differential fluid exceeds the cracking pressure of the check valve.

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: A method for making a liquid-chromatography apparatus includes inserting two inner conduits into an intermediate tube, inserting the intermediate tube into an outer tube, forming a proximal seal between the intermediate tube and at least one of the inner conduits, and forming a distal seal between the intermediate tube and at least one of the inner conduits. A liquid-chromatography apparatus includes an outer tube, an intermediate tube disposed in the outer tube, two inner conduits disposed in the intermediate tube, a proximal seal between the intermediate tube and at least one of the inner conduits, and a distal seal between the intermediate tube and at least one of the inner conduits.
