Single- and Double-Resonance Atomic Fluorescence Spectrometry with Inductively Coupled Plasma Atomization and Laser Excitation
Dye lasers pumped by an XeCl excimer laser were used to excite metal atoms in the inductively coupled plasma (ICP) for single- and double-resonance fluorescence spectrometry. The detection limits (3σ) obtained with the single-resonance approach for Ag(I), Au(I), Co(I), Ni(I),
Pb(I), Pd(I), Pt(I), and Sc(II) were 0.8, 4.2, 15, 3, 5, 0.7, 3.9, 3.3, and 0.2 ng/mL respectively; and with the double-resonance approach were 1.7, 6.0, 530, 5, 170, 8, 45, 29, and 13 ng/mL, respectively. Silver and lead were determined in an unalloyed copper standard reference material (#498)
by both approaches, and excellent agreement with the true values was found.
