Abstract [en]

Pulp and paper industries are interested in a technique for analysing the purchased resins used in coating colours. The concept of pyrolysis-gas chromatography in combination with chemometrics, i.e. principal component analysis and principal least squares, was used to develop improved methods for the quantitative analysis of tertiary mixtures based on latex resins. A principal least square model was made based on pyrolysis-gas chromatography data and a mass spectrometer was used to identify pyrolysis fragments. It was shown that the model accurately predicted the concentration of a resin in a tertiary mixture. The average error of prediction, for resin mixtures not previously shown for the model, was less than 4% by weight for each of the investigated resins.
