Abstract
The present disclosure provides an extraction coating for an SPME sampling instrument, where the extraction coating includes a sorptive material immobilized in a fluorocarbon polymer that is compatible with thermal-assisted desorption techniques, solvent-assisted desorption techniques, or both. The disclosure also provides SPME sampling instruments, methods of making an SPME sampling instrument, and methods of extracting an analyte from a sample matrix using the SPME coating.
Claims20
A solid-phase micro-extraction (SPME) coating comprising:
- a sorptive particulate material immobilized in a fluorocarbon polymer that is compatible with a thermal-assisted desorption technique, a solvent-assisted desorption technique, a solid sample desorption method, or a combination thereof.
A method of making a solid-phase micro-extraction (SPME) sample instrument, the method comprising:
- mixing a fluorocarbon polymer and a sorptive material in a solvent;
- applying the mixture to a support to form a substantially uniform SPME coating layer on at least a portion of the support;
- and
- removing the solvent.
