Abstract
Laser-induced fluorescence in a graphite furnace with an intensified diode array is used for determining ultratrace osmium. Fluorescence spectra of os mium were investigated in a wide spectral range for five excitation transit ions from the ground state. The optimum wavelengths of excitation and fluor escence were selected; the limit of detection of osmium in aqueous solution s is 50 pg.
