Abstract
An improved gas chromatography system is presented. The system comprises: an enclosure having an inlet and an outlet, such that the ventilation flow is from the inlet to the outlet; a chamber disposed in the enclosure; a monolithic gas analyzer disposed in the chamber and a temperature control unit disposed in physical contact with the chamber. The monolithic gas analyzer operates to separate and detect molecules from a gas; whereas, the temperature control unit is configured to control temperature inside the chamber.
Claims18
A gas chromatography system, comprising:
- an enclosure having an inlet and an outlet, such that ventilation flow is from the inlet to the outlet;
- a chamber disposed in the enclosure;
- a monolithic gas analyzer disposed in the chamber and operates to separate and detect molecules from a gas;
- and
- a temperature control unit disposed in physical contact with the chamber and configured to control temperature inside the chamber, where the enclosure includes a partition which separates the temperature control unit from the outlet.

A gas chromatography system, comprising:
- a chamber;
- a gas analyzer disposed in the chamber, wherein the gas analyzer includes a detector, a flow rate sensor and a preconcentrator arranged in the same plane of an integrated circuit;
- a temperature control unit arranged adjacent to the chamber and configured to control temperature inside the chamber;
- and
- a pump disposed outside of the chamber, wherein, during a sampling phase, the pump operates to draw gas into an inlet of the detector, such that the gas passes through the detector and into the preconcentrator and, during an analytic separation phase, the pump operates to reverse the flow of the gas, such that the gas moves from the preconcentrator and into the detector.
