Determination of Cobalt Content, Solids Content, Relative Density and Viscosity in Paint Driers using Vis-NIR Spectroscopy

This scientific poster shows the use of Vis-NIR spectroscopy for the simultaneous quantification of cobalt content, solids content, relative density and viscosity in paint driers. Each sample was acquired in transmission over the full wavelength range (400–2500 nm) using the NIRS XDS RapidLiquid Analyzer and then Vision, with its Partial Least Squares (PLS) algorithm, was used to develop quantitative prediction models for cobalt content. This is far superior to the conventional wet chemical laboratory methods as it has the advantage of the expanded wavelength range.
