Abstract: A chemical sampling system includes a direct analysis in real time (DART) device and an atmospheric pressure photoionization (APPI) device positioned proximate the DART device. Another chemical sampling system includes the APPI device positioned proximate to a thermal desorption device.
Abstract: A detection system assembly is provided. The detection system assembly includes a detector system including a housing having a sample port configured to receive a sample of an unknown substance, a detector assembly in flow communication with the sample port, and a pump in flow communication with the detector assembly. The detection system assembly further includes a dryer cartridge removably coupled to an outer surface of the housing of the detector system. The dryer cartridge is in flow communication with the pump and the detector assembly.
