A desorber for a trace detection system. The desorber includes an inlet configured to receive a sample, a heating element configured to generate a vapor from the sample, and an active cooling element configured to cool the desorber.

Rapid desorber heating and cooling for trace detection

Apparatuses and method are provided. For example, in one embodiment, a ring electrode includes a plurality of sub-rings adapted to provide an electric field inside a spectrometer. The sub-rings have an internal sub-ring radius. There is a ring insulator between adjacent sub-rings. Each said ring insulator has substantially the same internal radius as the sub-rings. In another embodiment, a method is provided for insertion of the ring electrode inside the spectrometer.
