Abstract
An extremely sensitive trace element detection technique in water is proposed and demonstrated, in which the excimer laser ablation is used to generate a densely atomized plume and the generated atoms are detected by sensitive laser-induced fluorescence (LIF) spectroscopy with a CW dye laser. Very strong LIF signal is detected without any interference of the plume radiation for 1 ppt, 10 μI Na water solution. A detection limit less than 0.1 ppt or 1 fg can be attained by this scheme.
