| This presentation will focus on the use of Raman spectroscopy for the analysis of solid (powders, pastes, slurries, etc.) samples with emphasis on online process analysis applications. Raman spectroscopy has the potential to be a very useful process analysis tool. Towards this goal, a novel high precision Raman probe for online process analysis will be demonstrated that provides enhancements in measurement precision by increasing the reproducibility and accuracy of optical sampling of high solid content samples. The ease of use of this new Raman probe and the increased sampling precision has lead to its use in various proofs of concept and online process analytical applications. These applications include dry powder-powder mixing efficiency, coating thickness measurements, solvent drying analysis, reaction monitoring and many other processes. In this presentation I will discuss the physical and optical design of the new Raman probe and demonstrate its applicability as an online sampling tool. |
