Abstract

Synthetic fibers which are microscopically indistinguishable could differ in chemical composition. The use of infrared spectroscopy to determine generic subtypes is standard forensic science practice. An improved technique is described for preparing good solvent cast films suitable for producing acceptable spectra from samples as small as 1 μg.

Keywords:
criminalistics, synthetic fibers, solvent cast film, spectroscopic analysis
