  • Method and system for trace detection of low volatile substances
    Patent number: 12181394
    Abstract: A system includes a conductive sampling swab including a non-mesh substrate and a thermal desorber including a clamping assembly configured to releasably hold the conductive sampling swab. The clamping assembly is configured to be electrically connected to a voltage or current source, and the thermal desorber is configured to resistively heat the conductive sampling swab to a temperature sufficient to vaporize a sample material disposed on the conductive sampling swab.
    Type: Grant
    Filed: September 9, 2021
    Date of Patent: December 31, 2024
    Assignee: ANALYTICAL DETECTION LLC
    Inventors: Andrey N Vilkov, Joseph Adam Widjaja, Jack Albert Syage
