Abstract: A hardware connector system is provided for connecting a tubing 4 to a threaded end fitting 8 in a High Performance Liquid Chromatography (HPLC) device. The connector system comprises: a conical ferrule 3, a threaded nut 2, and a threaded pre-swaging tool 5 for interacting with the threaded nut 2. In a pre-swaging step a wide end 12 of the conical ferrule 3 is gripped and pushed towards a pre-machined recessed groove 1 machined on the outer side of the tubing 4, so that the narrow end 11 of the ferrule 3 is deformed to engage with the groove 1. The ferrule 3 can hence be “locked in place” in the recessed groove 1 without excessive radial forces applied on the tubing 4. When the pre-swaging tool 5 is removed then the threaded end fitting 8 can be coupled to the threaded nut 2, or to another threaded nut 2. The threaded end fitting 8 has a receiving shape for receiving the conical ferrule 3.

Abstract: An electromembrane extraction (EME) device including a union connector, an acceptor compartment with a connector end and a donor compartment with a connector end wherein both connector ends are connectable to the union connector, wherein the union connector includes a flat membrane with a seal on each side thereof, wherein the seals when the acceptor compartment and the donor compartment are connected to the union connector are arranged respectively between the acceptor compartment connector end and the flat membrane and the donor compartment connector end and the flat membrane.
