  • Publication number: 20210316246
    Abstract: The disclosed embodiments relate to the design of a preconcentrator system for preconcentrating air samples. This preconcentrator system includes a plurality of preconcentrators that preconcentrate the air samples prior to chemical analysis, and a delivery structure comprising a manifold that selectively routes a sample airflow to the plurality of concentrators so that the plurality of preconcentrators receive a sample airflow concurrently or individually.

  • Publication number: 20190234906
    Abstract: One embodiment of the present disclosure provides an ion mobility spectrometry (IMS) device for performing chemical analysis. The IMS device includes a first set of electrodes arranged linearly in a first direction and separated by a first set of gaps. The IMS device also includes a second set of electrodes positioned directly opposing the first set of electrodes to match the first set of electrodes on a one-to-one basis, wherein the second set of electrodes are separated by a second set of gaps. The IMS device includes a drift region between the first set of electrodes and the second set of electrodes, wherein charged particles enter at a first end of the drift region and traverse the drift region along the first direction. The IMS device additionally includes a detector positioned at a second end of the drift region and configured to receive charged particles exiting the drift region.

  • Publication number: 20190137476
    Abstract: The disclosed embodiments relate to a technique for detecting Huanglongbing (HLB) infection in a citrus plant. This technique involves first gathering one or more samples of volatile organic compounds (VOCs) emanating from the citrus plant. Next, a system measures VOCs in the gathered samples to determine a VOC profile for the citrus plant, wherein the VOC profile comprises measured values for a set of VOCs that comprise disease-specific biomarkers for HLB infection. Finally, the system determines an HLB infection status for the citrus plant by analyzing the VOC profile.
