Abstract

A unitary distribution plate of a Gas chromatograph (GC) module having a plurality of valve bores disposed on a bottom surface of the unitary distribution plate and a least one sensor cell and at least one column port machined into the top surface of the unitary distribution plate. The valve bores and sensor cells are connected by fluid pathways within a thickness of the distribution plate. The pathways include a combination of planar, longitudinal, diagonal, and radial fluid pathways relative to the top surface of the distribution plate. The fluid channels are formed by diffusion bonding or more generally laminating multiple plates into the unitary distribution plate.
