Photoinduced nucleation: A novel tool for detecting molecules in air at ultra-low concentrations

This paper describes the development of a novel detection method and the demonstration of its capability to detect substances at concentrations as small as a few parts per trillion. It is shown that photoinduced nucleation is not in itself a nucleation process; rather, supersaturated vapor condenses...
