  • Micro Circulatory Gas Chromatography System and Method
    Publication number: 20210252480
    Abstract: A gas chromatography system can include a circulatory loop, a gas inlet positioned along the circulatory loop, a gas outlet positioned along the circulatory loop, a micro column positioned in line with the circulatory loop, and an in-line population sensor positioned in line with the circulatory loop. The in-line population sensor can be configured to detect changes in gas population. The gas inlet and gas outlet can be associated with a gas inlet valve and gas outlet valve, and configured to admit or withdraw gas from the circulatory loop, respectively. A gas sample can be circulated through the circulatory loop for at least one cycle, and a component of the gas sample can be detected using the in-line population sensor.
