The results of analysis of aerosol in aqueous NaCl solution by the femtosecond-pulse laser-induced breakdown spectroscopy (FS-LIBS) method are considered. Estimates are presented for the impurity (Na) concentration by the analytical pair method using the additive method. We chose, as an internal standard line, the radiation of the atomic nitrogen ion N+ at a wavelength of 500.515 nm, formed from atmospheric nitrogen molecules in the filamentation domain. A possibility of estimating the concentration of a chemical compound (NaCl) from emission of its constituent part (Na) in aqueous aerosol by the FS-LIBS method is interesting for developing the femtosecond lidar sounding techniques.
