H. Wilcken et Hr. Schulten, DIFFERENTIATION OF RESIN-MODIFIED PAINTS BY PYROLYSIS-GAS CHROMATOGRAPHY MASS-SPECTROMETRY AND PRINCIPAL COMPONENT ANALYSIS, Fresenius' journal of analytical chemistry, 355(2), 1996, pp. 157-163
The combination of pyrolysis (Py) with gas chromatography/mass spectro
metry (GC/MS) is already well established for polymer analysis. A firs
t approach is reported using this method for detailed quality monitori
ng of a complex technical polymer system. Six similar solvent-based pa
ints (one standard and five modifications) have been used for evaluati
on. The major pyrolysis products were identified and qualitative and q
uantitative modifications were detected and specified. Principal compo
nent analysis (PCA) was applied for visualization of differences and s
imilarities.
