Patent number: 7047661Abstract: A SPME-fiber cleaning and conditioning apparatus and method having an elongated heating chamber with first and second opposite ends. The first end is capable of insertably receiving a SPME fiber portion of a SPME device, and the second end is a fluid outlet. A heater is provided for heating the chamber and heat-treating an inserted SPME fiber. Contaminants and other particles are agitated, desorbed and purged from the inserted SPME fiber by flowing a fluid through the chamber from the first end to the second end, away from the SPME device. Additionally, turbulence may be produced in the flow at a location adjacent the first end, to enhance agitation, desorption, and purging. A holder may also be provided extending from the first end for supporting the SPME device in a substantially horizontal orientation when the SPME fiber is positioned in the chamber.Type: GrantFiled: April 22, 2003Date of Patent: May 23, 2006Assignee: The Regents of the University of CaliforniaInventors: Armando Alcaraz, Michael H. Wiefel

Patent number: 6749826Abstract: Airborne or aqueous organic compound collection using carbon nanotubes. Exposure of carbon nanotube-coated disks to controlled atmospheres of chemical warefare (CW)-related compounds provide superior extraction and retention efficiencies compared to commercially available airborne organic compound collectors. For example, the carbon nanotube-coated collectors were four (4) times more efficient toward concentrating dimethylmethyl-phosphonate (DMMP), a CW surrogate, than Carboxen, the optimized carbonized polymer for CW-related vapor collections. In addition to DMMP, the carbon nanotube-coated material possesses high collection efficiencies for the CW-related compounds diisopropylaminoethanol (DIEA), and diisopropylmethylphosphonate (DIMP).Type: GrantFiled: June 5, 2002Date of Patent: June 15, 2004Assignee: The Regents of the University of CaliforniaInventors: Thomas M. Tillotson, Brian D. Andresen, Armando Alcaraz
