Description
Summary:Laser ablation fast pulse discharge plasma spectroscopy (LA-FPDPS) technique is a recently developed atomic emission analytical technique that is analogous to dual pulse laser induced breakdown spectroscopy (DP-LIBS). LA-FPDPS, however, uses a periodical oscillating discharge plasma generation method on samples instead of the second laser beam in DP-LIBS. Here we describe the electric characteristics and its application to the analysis of Pb, Mg and Sn in soil. Due to the fast discharge process, the peak power deposition rate is up to 1.5 MW, although the discharge energy is relatively small. The main energy deposition process only last for ~ 4 μs. From the measured spectra, calibration curves for Pb, Mg and Sn in soil were derived and the limits of detection were 1.5 μg/g, 34 μg/g and 0.16 μg/g respectively.
