Publication number: 20220357305Abstract: A thermal module for pre-heating liquid flowing into a liquid chromatography column, includes a trough compartment with two ends, one of the two ends having an electrical socket, a first fluidic assembly, a second fluidic assembly, and a clamp assembly. The clamp assembly includes a rail configured to receive the first fluidic assembly. The clamp assembly includes a carriage slidably mounted to the rail and configured to receive the 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 clamp assembly, and to establish a second fluid tight seal between the second fluidic assembly and the chromatography column. The clamp assembly is disposed within the trough compartment, and the first fluidic assembly is plugged into the electrical socket at the one end of the trough compartment.Type: ApplicationFiled: July 14, 2022Publication date: November 10, 2022Inventors: Peter Kirby, Marcos O.

Patent number: 10232287Abstract: An apparatus for use in a liquid chromatography system includes a chromatography port and a tubing assembly having a chromatography tube coupled at one end to the chromatography port. The end of the tube has an end face covered with a corrosion-resistant material, for example, gold. The corrosion-resistant nature of the material protects the end of the tube from corrosion or erosion, which improves the quality and reliability of a seal between the end face of the tube and a sealing surface of the port. Alternatively, or in addition to covering the end face of the tube with the corrosion-resistant material, a gasket covered with or made of the corrosion-resistant material can be disposed between the end face of the tube and the port. This gasket extends the reach of the tube to facilitate bottoming out the tube within the port.Type: GrantFiled: March 4, 2013Date of Patent: March 19, 2019Assignee: WATERS TECHNOLOGIES CORPORATIONInventors: Kurt D. Joudrey, Steven D. Trudeau, Paul Keenan, Joseph A. Luongo, Daniel J. McCormick, Eugene Berthiaume
