Abstract
Experimental studies of electrical interferences in the dual laser ionization technique are reported and compared to those commonly encountered in laser-enhanced ionization spectrometry. For the dual laser ionization of sodium, the addition of easily ionized matrix components such as cesium, lithium, and potassium were found to have little or no effect on signal recovery. Similar results were obtained in experiments with lithium and strontium as the analytes. Some chemical interferences were found and discussed.Keywords
