Patent ID: 8668873

Claim:
A system for solid phase microextraction (SPME) and ion mobility spectrometry detection, comprising: an ion mobility spectrometer (IMS) having a sample receiving area comprising a device receiving region defined by a circular circumference within which a planar, circular, disc shaped device can reside; and a SPME device residing in the device receiving region for detection and characterization of a sorbed vapor, the SPME device comprising: a substrate having first and second opposed surfaces and one or more side surfaces integrally connected to the first and second surfaces, the first and second surfaces being circular and planar surfaces; a volatile compound sorptive coating disposed on the first surface and the second surface, wherein the volatile compound sorptive coating is exposed and capable of sorbing a vapor from a material selected from the group consisting of an explosive, a taggant in an explosive, a controlled substance, a biohazard, or mixtures thereof; wherein the SPME device has a thickness, as measured from the distance between the first and second surfaces, of about 0.5 mm to about 2 mm; and wherein a total surface area of the surfaces coated with the volatile compound sorptive coating is at least 25 mm 2 ; and wherein the SPME device resides in the device receiving region of the sample receiving area of the IMS such that the first and second surfaces are concentric with the device receiving region and the side surfaces are in contact with the circumference of the device receiving region.
