A Direct-Plating Method for the Precise Assay of Carbon-14 in Small Liquid Samples

Abstract

WHEN aqueous solutions containing carbon-14 compounds are dried on planchettes for assay under an end-window counter, surface tension often makes it difficult to ensure that the solids are deposited in a layer sufficiently uniform to give reproducible self-absorption and counter geometry. The essential feature of the present method is that the compound to be assayed is incorporated in a layer of gel which will dry to a perfectly even film.
