Abstract

An investigation was undertaken into extending the use of ESDA (Electrostatic Detection Apparatus) for the examination of marks on semi-charred documents. It was determined that marks could be recovered from paper heated to temperatures just before the paper carbonized.

Detailed investigations were also undertaken to develop Inductively Coupled Plasma-Mass Spectrometric (ICP-MS) and ICP-Emission Spectroscopic (ICP-AES)techniques to determine the provenance of paper, paper ash, ball-point, and fountain pen inks, and pencil leads, and to develop a revolutionary method for determining and tracing the chemical signature of ballpoint pen inks, directly on papers, using Laser Ablation based ICP-MS.
