Abstract

In usual optogalvanic spectroscopy in a flame, the signal is obtained by thermal ionization of selectively excited species. The optogalvanic signal in a flame was remarkably enhanced by selective multi-step photo-ionization, when an intense UV laser beam was applied into the flame. The enhancement factor exceeded 100 and a detection limit of 5 ppt (pg/ml) was obtained, when this technique was applied for tracing atomic Ca in water.
