| Abstract |
Laser Raman spectroscopy is evolving into a primary tool for the identification of molecular water pollutants. The study approaches the limits of detectivity of carbon disulfide and benzene to about 20 ppm in water solutions using a high-resolution Raman spectrometer, cooled detectors, and photon counting techniques. An optomized design for a pollution-measuring instrument is suggested, and a prototype has been built which is useful with any value of excitation energy short of sample degrading. The present instrument scans spectrum windows with fixed preselecting filters followed by a small single monochromator with high throughput. The resulting detectivity with 20 mw of laser power was only 1000 ppm. (Author) |
