The use of frequency-tunable dye lasers in atomic-fluorescence analysis has made it possible to lower significantly the limits of detection for most elements. In this work the commercially produced lamp-pumped dye lasers of the type LZhI were used as the excitation source, which made it possible, first of all, to simplify the design of the atomic-fluorescence spectrometer by eliminating the frequency doubling of the laser radiation and, second, to study the analytical possibilities of commercially produced dye lasers with microsecond lasing. The authors studied solutions of sodium, barium, potassium, calcium, nickel, cobalt, copper, and molybdenum salts. These elements were chosen based on the fact that they have absorption lines with different degrees of intensity in the region of generation of the most efficient rhodamine 6G dye laser.
