Abstract

It has been found that a simple gaseous electrical discharge can induce visible fluorescence in a variety of organic compounds separated on silica gel thin-layer chromatoplates. Exposure times ranging from 5 sec to 5 min are ample to detect submicrogram quantities with the unaided eye. The method is simple and convenient, and appears to have broad applicability to a wide variety of organic compounds. It is anticipated that this procedure will lend itself to sensitive quantitation by the use of spectrofluorimetric instrumentation.
