The analytical determination of nickel and tin by laser-excited atomic fluorescence spectrometry (LEAFS) is studied. Non-resonance nickel fluorescence near 340 nm is excited at several nickel lines near 300 nm and direct-line tin fluorescence at 317.5 and 380.1 nm is excited at the 300.9 nm line in a nitrogen-separated air-acetylene flame. Factors which affect detection limits and methods which can be used to improve them are discussed. The application of LEAFS to the determination of nickel and tin in several standard reference materials (river water, unalloyed copper, and fly ash) is investigated, including problems related to iron spectral interference encountered for analysis in these matrices.
