The poster shows the use of Vis-NIR spectroscopy for the simultaneous quantification of cobalt content, solids content, relative density and viscosity in paint driers as an outstanding alternative to conventional wet chemical laboratory methods. The advantages of the expanded wavelength range over the visible range become clear in this application: the visible range (400 – 780 nm) correlates directly with the cobalt content; the NIR range (780 – 2500 nm) is used for determining the chemical and physical parameters.
