The article presents information about orthogonal projection approach and related methods in process monitoring. It informs that process monitoring is one of the most challenging domains of analytical chemistry. It helps to control the process for instance by detecting perturbations in the process, by indicating when the end point of a reaction is reached and in general by controlling and helping to assure product quality. The traditional approach consists in inspecting the final product and in screening out items that do not meet the predefined specifications reflecting the quality of the manufactured product.
