Abstract: A fitting for coupling fluidic paths, such as high pressure fluidic paths in liquid chromatography systems, includes a compression nut, a tube assembly and a compression member. The compression nut has a threaded outer surface to engage a threaded bore of a receiving port and the tube assembly has an outer surface and an end face to contact a sealing surface of the receiving port. The compression member is pre-staked to the outer surface of the tube assembly at a predetermined distance from the end face and has a tapered surface to engage a surface of the receiving port. The predetermined distance permits the tube assembly to be inserted into the receiving port so that the end face makes contact with the sealing surface without the tapered surface engaging a surface of the receiving port and so that the threaded outer surface of the compression nut engages the threaded bore.

Abstract: Examples of gas liquid separators (50) include a chamber (52), a fluid mixture inlet (56), a gas outlet (62) and a liquid outlet (64). The fluid mixture inlet and the gas and liquid outlets are in fluid communication with the chamber. A fluid mixture received at the fluid mixture inlet diffuses inside the chamber and is separated into a liquid and a gas. The separated liquid is gravity-fed to the liquid outlet. In one embodiment the fluid mixture is conducted through piping (68), including a 90° elbow, to the fluid mixture inlet (56). Advantageously, the elbow can reduce the velocity of the fluid mixture before reaching the fluid mixture inlet (56). The gas liquid separators have reduced dispersion and increased liquid recovery in comparison to conventional gas liquid separators used for chromatographic separations. The reduced dispersion yields an improvement in the shape of chromatographic peaks.
