Summary
The suitability of laser Raman spectrometry in process control is demonstrated by comparing results obtained under standard measuring conditions and with special optical fibers. The applicability of capillary tubes which can improve sensitivity in remote sensing is investigated and possible distortions of Raman spectra sampled with optical fibers are described. In preliminary experiments with U(VI) solutions it could be shown that internal standardization using the 1650 cm−1 water band is possible in the process control of aqueous solutions.
