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.
