AI Technical Summary
Conventional fluidic couplings used in high-pressure chromatographic systems, such as UPLC, suffer from adverse chromatographic effects like carryover and peak tailing due to unswept volumes and corrosion at capillary interfaces.
A fluidic fitting with an integral face seal is developed, comprising an inner tube, an intermediate polymeric tube, and an outer metal tube. The intermediate tube is extruded during crimping, creating a seal when compressed against a coupling body, eliminating the need for a ferrule or separate seal component.
The integral face seal significantly reduces or eliminates unswept volumes, minimizing sample carryover and improving chromatographic measurement accuracy, while also preventing corrosion and simplifying handling by integrating the seal within the tube assembly.
