Reproducibility in counting by a gas-flow detector of duplicate samples of C14-labeled compounds plated on glass planchets is much improved by spraying of the lower surface of the planchet with an "antistatic" agent in aerosol form. Count rates that decreased with time were eliminated by this treatment.
