    Abstract

    Infrared spectroscopy (IR) is widely used in the forensic laboratory for the identification and comparison of materials such as explosives, drugs, paints, and plastics. These materials are often encountered as trace evidence. Consequently, the total sample available is so small that conventional IR techniques, even with micro-KBr pellets, are not feasible. The use of a high-pressure diamond cell sample holder suitable for the infrared analysis of microgram-sized samples was reported in 1961 [1]. Additional advantages of the diamond cell holder for use with solid samples are minimal sample preparation and applicability to a wide range of materials. Applications of the technique, however, have been limited by the commercial availability of a suitable device. Recently, studies have been reported on several materials of trace evidence interest including the characterization of vehicle paints [2] and the microanalysis of paints, plastics, and other materials [3].
