The Comparison of Black Polyvinylchloride (PVC) Tapes by Pyrolysis Gas Chromatography

CODEN: JFSCAS

Abstract

Pyrolysis capillary gas chromatography (Py-GC) was used to compare thirty black polyvinylchloride (PVC) tapes. A 0.5-mm square of tape (about 25 μg) was found to be an adequate sample size. Tests of within-roll homogeneity showed sufficiently consistent pyrogram patterns throughout to allow correct matches to be made. Twenty-six of the tapes gave pyrograms which were easily distinguishable from all the others. Fragments of tape recovered after the detonation of four improvised explosive devises were matched to the appropriate tape standards by Py-GC even when the fragments were partially burned.
