Laser-induced fluorescence with an OPO system. Part II: Direct determination of lead content in seawater by electrothermal atomization-laser-excited atomic fluorescence (ETA-LEAF)

Abstract

Fluorescence was induced by coupling a laser with an optical parametric oscillator (OPO) to develop an analytical method for the direct determination of lead content, at ultra-trace level, in seawater by electrothermal atomization-laser-excited atomic fluorescence (ETA-LEAF). The optimization of atomization conditions, laser pulse energy, and mainly temporal parameters allowed us to reach a 3 fg detection limit (0.3 ng L-1) despite the low repetition rate of the device. The expected error on predicted concentrations of lead, at trace levels, in seawater was below 15%. © Springer-Verlag 2003.
