FTIR Microscopy Analysis of Automobile Paints

In 2009, 246 million motor vehicles were registered in the US with 10.8 million of them being involved in an accident. Many of those accidents involved fatalities, hit-and-runs, and in general, uncertainty in accident cause and responsibility. Identifying potential subjects in an accident routinely involves the collection of paint chips or smears. This is especially the case in hit-and-run accident investigations where the strong need to link paint samples to the vehicles involved is apparent. Fortunately, vehicle manufacturers constantly change the chemical makeup of their paints which tend to make the paints used for particular model and year vehicle unique. Automobile paints are comprised of binders (resins), dispersants, additives, and dyes. All the components of paint exhibit unique spectral features when analyzed with Fourier Transform Infrared (FTIR) Spectroscopy.
