Sažetak
The aim of this work is to investigate the use of in-situ Raman spectroscopy for the monitoring of cooling crystallization process. For this purpose, Raman spectroscopy with a focused laser beam was utilized for the estimation of solution concentration and slurry density. The Raman signal depends on many factors, including the composition of the solid and liquid phase, as well as the size and shape of the crystals. [1] Therefore, the use of Raman spectroscopy for quantitative measurements is challenging and requires advanced chemometric methods. The concentration of an Active Pharmaceutical Ingredient (API), ceritinib was determined experimentally in a solution mixture of 90% acetone and 10% water. The goal was to build a calibration model for the estimation of ceritinib concentration during the crystallization process. Methods used to build the calibration models include Partial Least Square Regression (PLSR) and an Artificial Neural Network (ANN). During model development, various methods for spectra preprocessing were evaluated. In addition, different hyper parameters for the models were tested by ANN. The prediction performance used to evaluate the developed models was the root mean square error of prediction (RMSE). The model created with an artificial neural network proved to perform better than the partial least square regression model for the estimation of solution concentration, but were not able to predict slurry density with good accuracy.
