ABSTRACT:
Sample liquid is vaporized by a thermospray vaporizer with a heated capillary tube. The end of the capillary tube is inserted into a graphite tube furnace while the furnace and a vertical sample platform in the furnace is at an above-ambient deposition temperature. Vapor spray emerging from the capillary tube is directed at the platform. Sample substances are deposited on the platform while vaporized solvent is drawn off by a vacuum.
