Abstract
The disclosure describes embodiments of an apparatus including a first gas chromatograph including a fluid inlet, a fluid outlet, and a first temperature control. A controller is coupled to the first temperature control and includes logic to apply a first temperature profile to the first temperature control to heat, cool, or both heat and cool the first gas chromatograph. Other embodiments are disclosed and claimed.
Claims5
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.
