Abstract: A fluid multiplexer includes a manifold having a plurality of fluid conduits formed therein, a fluid input and a plurality of fluid connection points located on the manifold and fluidically coupled together via the fluid conduits, and a flow control module coupled to the fluid connection points, the flow control module configured to provide a plurality of blocking flows to the manifold to control the flow of a primary fluid through the fluid conduits.

Abstract: A seal forming a fluid tight connection between a gas chromatography column and a sample inlet assembly is disclosed. The seal is formed by a metal injection molding process. The seal has a first surface adapted for sealing with the sample inlet assembly and a second surface adapted for sealing with the column. The seal has an aperture extending between the first and second surfaces. A method of sealing a connection between a gas chromatography sample inlet assembly and a gas chromatography column is also disclosed. The method includes providing a seal as described above, compressing the first surface of the seal against an end of the inlet assembly, positioning the column in fluid communication with the aperture, and engaging the column with the second surface.
