A method of manufacturing a fitting for fluidic coupling in a chromatography system includes welding a tube sleeve and an inner tube at an endface of each of the tube sleeve and the inner tube to create a tube assembly having a welded tube assembly endface and polishing the welded tube assembly endface.

Fitting for fluidic coupling in a chromatography system

A fitting for fluidic coupling in a chromatography system includes a compression screw including an axial bore, a threaded portion, and a drive end, a tube assembly including a tube sleeve and an inner tube disposed through the sleeve, the tube sleeve and the inner tube each extending to an endface of the tube assembly, the tube sleeve including an outer surface, a seal body extending between a first endface and a second endface, the first endface abutting the endface of the tube assembly, the seal body including an outer surface, and a collar secured to the outer surface of the tube sleeve and the outer surface of the seal body. Other Fittings, Methods of manufacture of fittings, and methods of fluidic coupling are further disclosed.

A solvent reservoir filter for a liquid chromatograph system includes a first screen extending in a first plane, the first screen configured to filter solvent received through the first screen, a second screen extending in a second plane that is parallel to the first plane, the second screen configured to filter solvent received through the second screen, a main body extending between and connecting the first screen and the second screen, and a fluid outlet configured to expel solvent filtered by the first and second screens from the solvent reservoir filter. Methods of use and assembly of the solvent reservoir filter for a liquid chromatograph system are further disclosed.
