Improved technique for detecting fluorescent compounds on chromatograms

Fluorometric analysis

“…Samarium and Eu may be determined quantitatively by the fluorescence of their complexes with thenoyltrifluoroacetone or by the fluorescence of the suspension in organic bases as diphenylguanidine (442). Samarium in the concentration of 5 X 10~3% in Ce02 has been determined by the fluorescence of the solid pellet phosphor made by grinding the mixture with lead sulfate (307).…”

“…Improved methods have been proposed for fluorometry of chromatograms (74, 307). Low temperature fluorescence and phosphorescence data for 59 organic compounds were reported (127).…”
