A and C: Chemometric calibration model for glucose concentration using Infrared spectroscopy (a) and Raman spectroscopy (c). The model provides high precision and low deviations. The blue points represent the experimental data and the red points represent the respective model prediction. B and D: Application of the Infrared calibration model (b) and Raman calibration model (d) for monitoring and control of the glucose concentration in a cell culture process. The blue curves represent the measured data and the red curves the concentrations of the model prediction.
