摘要: An aerosol produced by laser ablation was transported into a graphite furnace with the inert gas flow and deposited after α-irradiation without an additional electric field of different polarity applied inside furnace. Using Nd:YAG pulsed at rate several kHz for each pulse about 20 ns duration, 300 kW peak power detection coherent forward scattering spectrometry in combination xenon continuum source, multi-element spectra analyte were recorded. The intensities measured on 283.1 nm line lead detected brass as function number pulses yielding analytical curves. Field enhancement deposition factor 103 found. capability spectrometric approach source allows use internal standards.
