Abstract
A simple but efficient procedure has been developed for the extraction and analysis of adhesives and toners on questioned documents. From the single extraction of a sample of document equivalent to approximately 1 cm of a printed line, it is possible to record both the infrared spectrum and the pyrogram of the compound of interest. Good sensitivity and reproducibility has been observed for the analysis of toner and adhesive samples and the technique has proved effective in actual casework. The application of the technique to the analysis of adhesive tapes, inks and correction fluids is under investigation.
