Abstract
An example system includes a conductive sampling swab and a thermal desorber comprising an induction coil. The thermal desorber defines an opening configured to receive at least a portion of the conductive sampling swab within an internal volume defined by the induction coil, and the thermal desorber is configured to inductively heat the sampling swab to a temperature sufficient to vaporize a sample material disposed on the sampling swab.
Claims20
A system comprising:
- a conductive sampling swab comprising a non-austenitic, non-martensitic spring steel;
- and
- a thermal desorber comprising an induction coil, wherein the thermal desorber defines an opening configured to receive at least a portion of the conductive sampling swab within an internal volume defined by the induction coil,
- wherein the thermal desorber is configured to inductively heat the sampling swab to a temperature sufficient to vaporize a sample material disposed on the sampling swab.

A method comprising:
- inserting a conductive sampling swab at least partially within an internal volume defined by an inductive coil of a thermal desorber;
- and
- inductively heating the conductive sampling swab, with the induction coil, to a temperature sufficient to vaporize a sample material disposed on the conductive sampling swab,
- wherein the conductive sampling swab comprises a non-austenitic, non-martensitic spring steel.
1 more element
A conductive sampling swab comprising:
- a non-mesh substrate comprising a non-austenitic, non-martensitic spring steel,
- wherein the non-mesh substrate is configured to be inductively heated to a temperature sufficient to vaporize a sample material disposed on the non-mesh substrate.
