The present invention relates to an apparatus and method for rapid flash-like volatilization of high and low vapor pressure components from liquid or solid emanators which is in contact with a point or localized heat source. Vaporization is promoted by a geometrically small electrically resistive heating...http://www.google.es/patents/US6909840?utm_source=gb-gplus-sharePatente US6909840 - Localized surface volatilization
