Abstract—
We have obtained limits of detection (LoD) of Al (396.15 nm), Ba (553.35 nm), Ca (422.67 nm), Mg (285.21 nm), Na (588.99 nm) and Mn (403.08 nm) in liquid-droplet aerosol by filament-induced spectroscopy (R-FIBS) using ultrashort laser pulses (60 fs, 800 nm, 4.4 mJ). The limit of detection of the Na by emission line (588.99 nm) in a liquid-droplet aerosol was obtained by laser induced breakdown spectroscopy (LIBS) using short laser pulses (7 ns, 1064 nm, 550 mJ). The obtained results were compared within the framework of the methods used.
