Abstract:
1. A gas analysis system comprising: a substrate; a cascaded gas chromatograph having a fluid inlet and one or more fluid outlets and being mounted to the substrate, the cascaded gas chromatograph comprising: one or more detector arrays having a fluid inlet and a fluid outlet and being mounted to the substrate, wherein the fluid inlet of each of the one or more detector arrays is fluidly coupled to a corresponding one of the one or more fluid outlets of the cascaded gas chromatograph; a control circuit coupled to the cascaded gas chromatograph and to the detector array, wherein the control circuit can communicate with the first and second gas chromatographs and with the one or more detector arrays; a readout circuit coupled to the one or more detector arrays and to the control circuit, wherein the readout circuit can communicate with the control circuit and the one or more detector arrays; a pre-concentrator having a fluid inlet and a fluid outlet, wherein the pre-concentrator is mounted on the substrate and coupled to the control circuit, and wherein the fluid outlet of the pre-concentrator is coupled to the fluid inlet of the cascaded gas chromatograph; a filter and valve unit having a fluid inlet and a fluid outlet, wherein the filter and valve unit is mounted to the substrate and coupled to the control circuit, and wherein the fluid outlet of the filter and valve unit is coupled to the fluid inlet of the pre-concentrator; one or more pumps having a fluid inlet and a fluid outlet, wherein each pump is mounted on the substrate and coupled to the control circuit, and wherein the fluid inlet of each pump is coupled to the fluid outlet of a corresponding detector array; and a shroud covering the filter and valve unit, the pre-concentrator, the cascaded gas chromatograph, the one or more detector arrays and the pump.
