Gas Chromatography of Uranium Hexafluoride at Low Temperatures

Abstract

Gas chromatography of UF 6 at low temperature was studied with the use of columns of polytrifluoromonochloroethylene oils as liquid phase. The dependence of retention time and HETP of UF 6 on (1) degree of polymerization of oils, (2) liquid phase loading, and (3) kinds of solid support were studied in the temperature range between -10° and 40°C, and the most favorable conditions for quantitative analysis of UF 6 are discussed.The relation between the gas chromatographic characteristics of the columns and the B.E.T. surface area of the solid support has been briefly examined.
