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

An ionization chamber. The ionization chamber includes a vessel, an ionization source, an ion gate, and a mid-ring electrode. The vessel defines an ionization region. The vessel includes a first end axially disposed opposite a second end. The ionization source is located at the first end and generates ions. The ion gate is located at the second end of the vessel. The mid-ring electrode is located between the ionization source and the ion gate. During an ion compression stage, the ionization source is charged to a first ionization source potential, the ion gate is charged to a first ion gate potential, and the mid-ring electrode is charged to a first mid-ring potential that is less than the first ionization source potential and the first ion gate potential. The first mid-ring potential is configured to generate a potential well proximate the mid-ring electrode. The ions collect at the potential well.

A detection system for identifying an unknown substance includes a detector assembly configured to receive a particulate or vapor and determine a substance contained within the collected vapor or particulate sample, and at least one heater element operatively coupled in flow communication with the detector assembly. The heater element is configured to attract an airborne vapor when the detection system is in a vapor mode, and desorb at least a portion of the attracted particulate when the detection system is in a particulate mode.
