Selective Heavy-Atom Perturbation for Analysis of Complex Mixtures by Room-Temperature Phosphorimetry


Journal Article

The technique of selective external heavy-atom pertubation (SEHAP) is applied to improve room temperature phosphorescence (RTP) analysis of complex samples. It is demonstrated that heavy atoms can selectively increase the phosphorescence emission of specific components in mixtures. The usefulness of many heavy-atom perturbers has been investigated for a wide variety of polynuclear aromatic compounds of environmental interest in coal-derived products. The SEHAP technique extends the analytical possibilities of RTP analysis since targeted components in complex samples can be selectively monitored. © 1979, American Chemical Society.
