1. A distribution plate of a gas chromatograph module comprising:
a unitary top surface and a bottom surface defining a thickness;
a plurality of apertures disposed on the top surface extending partially into the thickness;
a plurality of valve bores disposed on the bottom surface extending partially into the thickness,
wherein the plurality of valve bores are arranged in a series of ring-shaped grouping patterns about a center axis of the distribution plate; and
a plurality of fluid pathways disposed within the thickness fluidly connecting the plurality of valve bores to the plurality of apertures,
wherein the plurality of fluid pathways comprises pathways positioned both longitudinally and in-plane relative to the top surface, and pathways positioned radially about the center axis,
and wherein at least one valve fluid pathway of the plurality of fluid pathways fluidly connects adjacent valve bores of the plurality of valve bores.
