Abstract:We report the design of an ultrahigh vacuum compatible vapor dosing system for organometallic compounds. A unique feature of this doser is the elimination of all metallic surfaces in order to reduce the reactivity of the organometallic molecules towards the doser walls. The vapors only come in contact with glass, Teflon, and Kalrez and the doser is heatable to temperatures of 150 °C. A novel modification to a commercial glass stopcock is described. These modified valves are used in the doser to seal the ultrah… Show more
