Paper Abstract

Spectroscopic studies have been done on crystallization and other reactions that undergo multiple phase changes. As the reaction opacity changes the spectral information is processed to determine which mode of measurement is optimal: reflectance or interactance immersion. A near IR spectrophotometer equipped with a unique probe is used which allows for optimal process monitoring with a single probe, rather than using multiple process interfaces to accommodate the change in the reaction medium. A with any near-IR method, models are created to allow for reproducible predictions of the phase changes that occur, and can also be used to quantitate the extent of reaction, the system composition, and other parameters.
