Hand-held trace vapor/particle detection system

摘要

A hand held detector system that has a housing with a passage that can receive a sample, and a concentrator that captures the sample. The hand held system further includes a single detector coupled to the concentrator and a fluid system that provides fluid communication between the housing passage and the concentrator, and between the concentrator and the detector. The system is powered by a battery. The system may include a controller that heats the concentrator with a temperature profile that causes a first trace molecule to desorb at a time different from the desorption of a second trace molecule. The system and components may be powered by a battery.
