Simple Fluorescent Intensification Screen for Ultraviolet Scanner Cameras

Chromatography

“…Many organic substances give fluorescent spots with quinine sulfate or sulfosalicylic acid (982). Ultraviolet-absorbing materials can be photographed through a fluorescent intensification screen (889). An elastic scale may be used for rapid determination of Rf values (1054).…”

Fluorometric Analysis

“…(198). Fluorescent screens for ultraviolet absorption can be made by impregnating filter paper w'ith an ethanolic solution of 1-methyl-4-(5-pentyl-2-oxazoyl) pyridinium toluene-p-sulfonate (280). These are used to detect ultraviolet absorbing substances.…”
