The feasibility of electrostatic precipitation of clustered lithium ions for removal of gaseous trace contaminants from atmospheres could not be demonstrated under the constraints imposed on the experimental work. The major difficulty was that the thermionic source cause oxidation of the contaminants acetone, methanol, and propane at 1-25 ppm concentration. The source was designed to minimize thermal effects such as oxidation and consume about the minimum practical heating power density to produce the necessary ion current in atmospheres near 760 torr pressures. Even at trace concentrations of oxygen in nitrogen, the oxidation rates were sufficient to obscure any possible precipitation effects.
