Thin-layer chromatographic separation on layers heavily loaded with powdered scintillators for luminescence detection of radionuclides

Abstract

Experiments are reported demonstrating that interference is not necessarily caused in a chromatographic separation on standard thin layers by the admixture of powdered scintillators. The study is of importance in connection with a sensitive method of radionuclide detection by β-radioluminescence (either scintillation fluorography on photographic film material or by direct photoelectric detection). Kieselguhr-, silica gel-, and cellulose thin layers were prepared containing various proportions of either an inorganic or organic scintillator (zinc silciate or anthracene, respectively). Mixtures of carbohydrates, phospholipids, and amino acids were tested as representative systems with suitable layers and developing solvents.
