An Improved Technique for Preparing Solvent Cast Films from Acrylic Fibers for the Recording of Infrared Spectra
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.
