  • PORTABLE MICRO-PRECONCENTRATOR TO FACILITATE CHEMICAL SAMPLING AND SUBSEQUENT ANALYSIS
    Publication number: 20220387924
    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.
    Type: Application
    Filed: August 10, 2022
    Publication date: December 8, 2022
    Applicant: The Regents of the University of California
    Inventors: Cristina E. Davis, Michael K. LeVasseur, Raquel Cumeras, Yuriy Zrodnikov, Mitchell M. McCartney, Alexander G. Fung, Daniel J. Peirano
