Abstract
Subject headings
Close
- Laser-induced fluorescence in a graphite furnace with an intensified diode array is used for determining ultratrace osmium. Fluorescence spectra of osmium were investigated in a wide spectral range for five excitation transitions from the ground state. The optimum wavelengths of excitation and fluorescence were selected; the limit of detection of osmium in aqueous solutions is 50 pg.
