Two pulsed dye lasers pumped by an excimer laser are simultaneously directed into the analytical zone of an inductively coupled argon plasma. When the two beams are tuned to the appropriate ionic transitions, highly excited ionic levels can be effici

Using strontium atoms present as a trace constituent in an air-acetylene flame as an example, a rich laser enhanced ionization spectrum was obtained. One pulsed tunable dye laser was tuned to a transition originating from the ground state (460.73 nm)

Absolute number densities for the metastable and radiative 4s argon levels in an inductively coupled plasma have been determined for a variety of plasma conditions by the technique of continuum source absorption. As primary source, a 300 W xenon arc

Four major types of spectroscopic systems for quantitative analysis of one or more spectral components we compared, with regard to signal-to-noise ratio for constant analysis time. These four methods are based on sequential-linear scan, sequential-sl
