We were approached by company who wanted to determine the end-point of a batch production process. If the reaction was allowed to continue beyond the end point it resulted in the build-up of unwanted by-products and reduced yield. They had tried UV-Vis spectroscopy without success. We investigated Mid-IR, Raman, NIR and UV-Vis on their products. It emerged that UV-Vis was in fact the best technique for this application but the sampling technique that they had tried was not well suited to the product. We introduced the new sampling technology, implemented the spectrometer and reaction control
RESULT: 27% increase in yield, elimination of unwanted by-products
