Abstract:
The assessment of quality is one of the most important parts of the manufacturing process. To do so, a constant monitoring of the product properties has to be done. In the case of polyester resins, the acid value and the viscosity are the properties to control to assure the perfect production of the product. To achieve this goal, the implementation of NIR spectroscopy could be very useful. With this in mind, in this bachelor’s thesis, the objective is the application of NIR spectroscopy and the development of a Partial Least Squares (PLS) calibration method so that the determination of the properties mentioned above can be performed.
