The application of such technology promises to augment much of today's process control, in-vivo medical diagnostics and environmental instrumentation. The use of optical fibers in chemical analysis is an attractive choice for many reasons. These include inrniunity to electromagnetic and RF interferences, lew attenuation, ruggedness, and of course suitability for in-situ on line monitoring in hazardous and/or remote environments. Fluorescence spectroscopy is an inherently sensitive technique; however, single wavelength measurements can be limited for analysis of complicated multiccnponent samples. In this regard, multidimensional fluorescence can be used to obtain additional information about the sample. In multidimensional fluorescence, the fluorescent measurement involves the use of multiple luminescence parameters to increase the specificity of the measurement. In this paper, the use of a newly designed fiber optic based multidimensional f luorometer to study the effects of various environmental pollutants on the spectral characteristics of marine phytoplankton is demonstrated.
