“…An extremely simple pyrogram was produced, consisting of a single peak of n-butyl methacrylate (nBMA) monomer, which indicated that the acrylic binding medium is a poly n-butyl methacrylate (pnBMA) homopolymer, and that on pyrolysis it undergoes complete depolymerization (a mechanism common to all polymethacrylates [22]), as shown in Figure 1. Figure 2a shows a pYrogram of Paraloid F-10 (Rohm and Haas)-the acrylic binder used in acrylic solution paints-with the mass spectrum of nBMA.…”

This paper describes the application of pyrolysis-gas chromatography-mass spectrometry (PyGCMS) to the characterization of an extensive range of synthetic paint types. Household and industrial paints, both of which have been formulated with polymers such as alkyd, polyvinyl acetate (PVA) and nitrocellulose, are included in this study, in addition to the acrylic solution and acrylic emulsion paints that were made specifically for the artists' market. The pyrograms obtained by PyGCMS were characteristic to each paint type and their principal diagnostic features are discussed. Apart from using the mass spectra produced by electron impact (EI) to confirm the identity of every peak, two additional analytical features of the mass spectrometer were shown to be particularly useful in this study. Chemical ionization (CI) was used to assist with the identification of unknown peaks through molecular weight determination. Selected ion current (SIC) monitoring, where the mass spectrometer only scans for specific masses, was successfully used for the detection of peaks of low intensity or those hidden by a more abundant material with a similar retention time.

“…Pyrolysis–gas chromatography can provide additional information for the polymers of chemically similar paints (11–14). However, this method is a destructive test, and the samples can be consumed by the high temperatures used during the analytical process.…”

High-energy synchrotron radiation x-ray fluorescence spectrometry (SR-XRF) utilizing 116 keV x-rays was used to characterize titanium dioxide pigments (rutile) and automotive white paint fragments for forensic examination. The technique allowed analysis of K lines of 9 trace elements in 18 titanium dioxide pigments (rutile), and 10 trace elements in finish coat layers of seven automotive white paint fragments. High-field strength elements (HFSE) were found to strongly reflect the origin of the titanium dioxide (TiO(2)) pigments, and could be used as effective parameters for discrimination and classification of the pigments and paint fragments. A pairwise comparison of the finish coat layers of seven automotive white paint fragments was performed. The trace elements in the finish coat layers detected by the high-energy SR-XRF were especially effective for identification. By introducing the trace element information of primer and electrocoat layers, all the automotive white paint fragments could be discriminated by this technique.
