PYROLYSIS CAPILLARY GAS CHROMATOGRAPHY/MASS SPECTROMETRY FOR ANALYSIS OF AUTOMOTIVE PAINTS
Pyrolysis capillary gas chromatography/mass spectrometry was used to analyze automotive paints. The mass spectral data from the entire chromatogram of a given paint was combined using an INCOS 2000 data system. This composite spectrum, after subtraction of background, was then stored in a library. Tentative identification of an unknown was effected by using the pattern recognition algorithm of the data system to search the library for the best comparison to the composite mass spectrum of the unknown. Although only a small portion of the samples from the FBI National Automotive Paint File was used, results showed good discrimination when a combination of the mass spectral and chromatographic data was utilized. Preparation of a searchable data base with the potential for widespread use is demonstrated.
