Abstract

The laser-induced photoacoustic spectroscopy (LPAS) has been developed [1 - 4] and successfully applied for the chemical speciation of aquatic actinide ions in trace concentrations [4 - 6]. Additionally, LPAS has been used for analytical applications, e.g. for trace detection of inorganic contaminants [7]. The method is found to be compatible with the conventional UVNIS spectroscopy in the spectral range of available dye lasers but having a distinctive advantage for the speciation sensitivity. However, the main difficulty for a routine laboratory use of LPAS has been a detection unit for acoustic signals generated within a given sample solution.
