Abstract
Recent work1 has experimentally measured temporal gating parameters that optimize the signal-to-noise ratio for six of the Resource Conservation and Recovery Act (RCRA) metals, arsenic, beryllium, cadmium, chromium, lead, and mercury. This work was accomplished at relatively large laser pulse energies (175 and 330 mJ / pulse), and over a wide range of temporal delay (2 – 50 µs) and gating (2 – 150 µs) in various combinations. This work concluded that each element had a distinct optimum in the delay and gate yielding the best signal-to-noise ratio.
