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.

Abstract: Devices, systems, and methods for explosion resistance include an analysis compartment isolated from a control compartment. A feed-through extends between the analysis compartment and the control compartment for extension of cabling therethrough, the feed-through hermetically sealed to block against flow of fluids between the analysis and control compartments.

Abstract: Devices, systems, and methods for explosion resistance include an explosion-resistant enclosure and a lid assembly. The lid assembly includes a lid for enclosing an opening of the explosion-resistant enclosure, and a graphical display assembly for presenting visual information regarding the analysis equipment.
