  • THERMAL PRECONCENTRATOR FOR COLLECTION OF CHEMICAL SPECIES
    Publication number: 20080184886
    Abstract: A thermal preconcentrator unit and a method for concentrating chemical species. The thermal preconcentrator unit includes a thermoelectric device having a temperature controlled surface and a sorbent material configured to concentrate the chemical species. The sorbent material is disposed on and in thermal contact with the temperature controlled surface. The thermoelectric device is configured to cool and heat the temperature controlled surface to promote sorption and desorption of chemical species onto and from the sorbent material. The method provides a temperature controlled surface and exposes the chemical species to a sorbent material disposed on the temperature controlled surface to concentrate the chemical species thereon.
