1. An apparatus comprising:
a first gas chromatograph including a fluid inlet, a fluid outlet, a first temperature control, and an integrated first Y-splitter;
a second gas chromatograph including a fluid inlet, a fluid outlet, a second temperature control, and an integrated second Y-splitter fluidly coupled to an integrated flow rate restrictor; and
a third gas chromatograph including a fluid inlet, a fluid outlet, a third temperature control, and an integrated third Y-splitter fluidly coupled to an integrated flow rate restrictor;
wherein:
the first Y-splitter is fluidly coupled to the fluid outlet of the first gas chromatograph,
the second Y-splitter is fluidly coupled to an outlet of the first Y-splitter, the fluid inlet of the second gas chromatograph, and an outlet of the flow rate restrictor integrated with the second gas chromatograph, and
the third Y-splitter is fluidly coupled to another outlet of the first Y-splitter, to the fluid inlet of the third gas chromatograph, and an outlet of the flow rate restrictor integrated with the third gas chromatograph.
