摘要： A selective-sorting system for aerosol droplets in human breath includes a mouthpiece to receive a flow of human breath, and a flow path coupled to the mouthpiece. This flow path includes one or more bends that cause the flow of human breath to change direction, which causes aerosol droplets in the flow having different mass-sizes to change direction at different rates. Moreover, the flow path is shaped so that droplets that change direction at different rates are directed to different destinations. The system also includes a collection path, which is coupled to the flow path so that aerosol droplets meeting a specific mass-size criterion are directed into the collection path. A condenser tube is located in the collection path, wherein the condenser tube includes a cooling mechanism that cools the condenser tube to facilitate condensing aerosol droplets to sides of the condenser tube for subsequent collection.

摘要： 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 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.

摘要： 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.
