A comparison of pyrolysis–gas chromatography–mass spectrometry and fourier transform infrared spectroscopy for the characterisation of automative paint samples Original Research Article

It has been shown that by using pyrolysis–gas chromatography–mass spectrometry (Py-GC-MS), it is possible to discriminate between a variety of base coat, solid paint and clear coat samples of automotive paints in commercial use from a wide range of car manufacturers. Some of the solid paints and clear coats were pairs of samples indistinguishable by fourier transform infrared spectroscopy (FT-IR).
