A fiber optic LIF (Laser induced fluorescence) EEM (Excitation emission matrix) for instrument for CPT deployment has been successfully developed and field tested. The system employs a Nd:YAG laser and Raman shifter as a rugged field portable excitation source. This excitation source simultaneously produces > 20 beams of differing wavelength in the UV that can be selectively chose for launch into fiber optics. The system uses a pair of silica-clad-silica optical fibers for each of its channels (eight of which were used in the work described), one to deliver excitation light from the multi-wavelength laser excitation source to the sample, and the other to conduct contaminant fluorescence to a grating spectrograph which utilizes a charge-coupled device detector to record fluorescence intensity as a function of both excitation and emission wavelength. The system has automatic data acquisition (depth and LIF) and some real time data analysis capability. The instrument has undergone several different calibrations including wavelength, analyte concentration, and standard compound fluorescence as a function of incident energy. Many sample types have been characterized in the laboratory including single components on sands of different particle sizes and clay, and fuel mixtures in solution and on sands.
