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.
Claims (17)
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.
2. The apparatus of claim 1 , further comprising a valve fluidly coupled to an inlet of the flow rate restrictor integrated with the second gas chromatograph and an inlet of the flow rate restrictor integrated with the third gas chromatograph.
3. The apparatus of claim 2 , further comprising a source of a secondary carrier fluid coupled to the valve.
4. The apparatus of claim 1 , further comprising:
a detector array coupled to the outlet of the second gas chromatograph; and
a detector array coupled to the outlet of the third gas chromatograph.
5. The apparatus of claim 1 , further comprising a controller coupled to the first temperature control, the second temperature control, and the third temperature control, wherein the controller 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,
a second temperature profile to the second temperature control to heat, cool, or both heat and cool the second gas chromatograph, and
a third temperature profile to the third temperature control to heat, cool, or both heat and cool the second and third gas chromatographs.
