✦ Synopsis

Laser-induced breakdown spectroscopy was applied to the determination of FeO( OH) in water and successfully determined the concentration of the turbid solution down to a few ppm ( pg ml-') . A Q-switched Nd:YAG laser, which delivered 8 ns pulses, was used as an excitation source. Cell-less measurement was achieved using a coaxial nozzle flow system which allowed to study the effect of ambient gas on emission intensity and decay lifetime of the breakdown plasma. Using helium gas and with a proper timing gate, the FeO( OH) concentration in water was determined in the ppm range.

The line-broadening mechanism for three emission lines (510.55, 515.32, and 521.82 nm) in laser-induced copper plasma was investigated by time-resolved laser-induced breakdown spectroscopy. Two emission lines observed at 515.32 and 521.82 nm revealed a dramatic decrease in linewidth as the delay of
