Abstract
A multiport gas chromatograph valve includes a first plate, a second plate, and a diaphragm. The first plate has a first plurality of ports and a second plurality of ports. The first and second plurality of ports are interposed with one another such that each of the first plurality of ports has a pair of neighbors from the second plurality of ports and each of the second plurality of ports has a pair of neighbors from the first plurality of ports. The second plate has a first activation port and a second activation port, the first activation port being fluidically coupled to a first plurality of gas slots, and wherein the second activation port is fluidically coupled to a second plurality of gas slots. The diaphragm is disposed between the first and second plates and has a first plurality of gas pockets that, when pressurized by the first plurality of gas slots, seals against the first plate to obstruct flow between each port of the first plurality of ports and a respective neighbor on a first side, and wherein the diaphragm has a second plurality of gas pockets that, when pressurized by the second plurality of gas slots, seals against the first plate to obstruct flow between each port of the first plurality of ports and a respective neighbor on a second side.
