A Remote Sensing Laser Fluorometer Available to Purchase

A variety of water quality parameters are accessible to measurement using the technique of fluorescence spectroscopy. These include such measurements as oil, chlorophyll, lignin sulfonate, and dye tracing. The availability of reliable lasers has opened up the possibility of using the fluorescence technique as a water quality analytical tool without being in direct contact with the body of water. For instance, it is possible to monitor oil on water from such remote locations as a bridge, boat, or aircraft. A system based on a helium cadmium laser is described and some experimental results on different materials from various locations are discussed.
