ABSTRACT:
A flow control device for a gas chromatograph is provided. The flow control device includes first and second valves each having alpha and beta operating states and a plurality of ports. In each of the first and second valves, the ports are associated to have alpha pairs of the ports and beta pairs of the ports. In the alpha operating state of each of the first and second valves, the ports in each of the alpha pairs are connected and the ports in each of the beta pairs are disconnected. In the beta operating state of each of the first and second valves, the ports in each of the beta pairs are connected and the ports in each of the alpha pairs are disconnected. The first and second valves are formed by a cylindrical manifold plate disposed between cylindrical first and second port plates. A first diaphragm is disposed between the first port plate and the manifold plate and a second diaphragm is disposed between the second port plate and the manifold plate.
