Abstract

A description of resonance-enhanced laser-induced plasma spectroscopy for elemental analysis was presented. It was found that the analyte signal-to-noise ratio increased from four to over fifty if the plume was reheated. Results showed that the enhancement was not due to resonance photoionization, instead rekindling of a larger plume volume was the mechanism responsible.
