Application of Differential Interference Contrast Microscopy to the Examination of Paints

CODEN: JFSCAS

Abstract

The value of paint flakes as evidence has been described throughout the forensic science literature. Experimental procedures and techniques as well as testing sequences have been reported in some detail by May and Porter [1], Crown [2], and Gothard [3]. Modern instrumental methods such as neutron activation analysis [2, 4], X-ray fluorescence [5], atomic emission spectroscopy [2, 6], pyrolysis gas chromatography [3, 7], and spectrophotometry [1, 2, 8] have been applied to effect a greater degree of discrimination. The use of solubility testing, color change with acids and bases, and thin-layer chromatography has been advocated for some time [6, 9]. The most prosaic of tests, microscopic comparison of color, layer sequence, and surface texture, has recently received attention by Gothard [3] and Fouweather et al [10].
