ABSTRACT
In many different fields of analytical chemistry, there is a constant need for more and more performant analysis methods. To be performant, such methods should allow an easy, fast and cheap analysis of a wide variety of products. Therefore, near-infrared (NIR) spectrophotometry has become one of the most powerful techniques in analytical chemistry [1-5], because of the following advantages:
1. NIR spectrophotometry enables the analysis of a wide variety of samples, including for instance strongly absorbing samples or opaque solid materials.
