FTIR Spectroscopy, Micro & Bench Techniques
FTIR is a spectroscopic technique in which infrared light is passed through a sample, which has the characteristic adsorption frequencies in the infrared region. This produces an infrared spectrum which looks like a series of peaks and valleys on an X/Y graph. This spectrum is unique for a given organic material and can be thought of as the materials chemical fingerprint. This technique is useful both for routine material verification/identification of polymers and identification of trace contaminates via the FTIR Microscope. Micro-FTIR spectroscopy is performed on a Bio-Rad UMA-250 microscope which is capable of obtaining spectra of objects down to about 25 microns in size. Micro-FTIR is widely used for identification of trace contaminates on manufactured items.
