Two spectrophotometric process monitors, one optimized for high concentration (approximately 10 g/L) and one for trace levels (approximately 10 ppm),were developed at Argonne and installed at the SRS H-Canyon facility for field testing. These systems were built of Commercial-Off-The-Shelf components utilizing a custom, facility-specific hardware interface. The systems directly provide a qualitative measurement of process chemistry (i.e. valence state). With appropriate calibrations the systems could provide quantitative data. Laboratory tests were performed to determine the spectrophotometric molar absorptivity coefficients for relevant actinide and transition metals of interest.
