Abstract

It’s shown that the increasing of electron impact excitation rate constant lead to increasing of line intensity, so the limit of detection (LOD) is lower. For femtosecond laser plasma generated on the sea water surface, the relation of the detection limits will be LOD(Na) < LOD(Ca) < LOD(Mg). The fact that the atomic line of Ca I 422 nm is more sensitive for femtosecond laser-induced breakdown spectroscopy is described.
