Plasma Cavity Ringdown Spectrometer for Elemental and Isotopic Measurements: Past, Present, and Future
Recent studies using Plasma Cavity Ringdown Spectroscopy (plasma-CRDS) show much promise of this newly developed technique for ultra-sensitive elemental/isotopic measurements. Plasma-CRDS, since its introduction in 1997, has experienced three major stages: (i) the early stage demonstration of the technical feasibility, (ii) the recent advancement on its technical improvements and extensive applications for elemental/isotopic measurements as well as plasma diagnostics and (iii) the most recent progress on the improvement of the instrument configurations based on a diode laser-compact microwave plasma-CRDS. Research and development in many aspects of this technique is vigorously under processing in our laboratories. This paper reports a brief review on the plasma-CRDS technique, its applications and the most recent advancement. Discussions on future developments toward a new generation of plasma- CRDS-based spectrometers for ultra-sensitive elemental/isotopic measurements are also presented.
