A Novel Pyrolysis Technique for Micro Paint Analysis

Abstract

The recent advancement of highly specialized instrumentation and instrumental techniques has enabled the forensic scientist to analyze paint samples in the microgram and picogram ranges. The limiting factor is often the physical recovery of small samples for microchemical analysis. A number of chemical procedures have been employed for the microanalysis of paints. Both infrared spectrophotometry (IR) and pyrolysis-gas chromatography (PGC) are popular techniques for the identification and comparison of paints.

New methods of chemical analysis—a tool for the conservator

“…For the identification of organic binding media [138] and complex mixture of polymerized substances, combinations of MS with the chromatographic (TLC, HPTLC, GC) or pyrolytic methods are proposed in the literature [29,[139][140][141]. A combination with IR techniques is also a powerful possibility [141][142][143].…”
