Abstract
An infrared spectroscopy method is described which requires little sample preparation and may be used for analysis of a wide range of samples of interest to forensic science. A small quantity of a sample is rubbed onto an abrasive silicon carbide disk, which is then measured by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The technique has been successfully applied to the infrared analysis of paint, synthetic rubber, cosmetics, corrector fluid, and adhesives.
