Abstract
The present invention is directed to a method and device to generate a chemical signature for a mixture of analytes. The present invention involves using a SPME surface to one or both absorb and adsorb the mixture of analytes. In an embodiment of the invention, the surface is then exposed to different temperature ionizing species chosen with appropriate spatial resolution to desorb a chemical signature for the mixture of analytes.
