Fourier Transform Infrared Spectroscopy

Fourier transform infrared (FT-IR) spectroscopy is a technique used for the identification of chemical functional groups in samples. In pure materials and simple mixtures, a complete identification of all components often is possible from the “finger print” region of the spectrum.

Polymer Diagnostics, Inc. uses this technique to characterize polymer and additive composition, to verify the identity of raw materials, to identify the composition of contaminants, to characterize reaction products, and to study the surface make-up of samples.

Advanced Capabilities with FT-IR Spectroscopy

By way of a transmission experiment, this technique can determine the identities of hard and soft solids, liquids and gases. An attenuated total reflectance (ATR) apparatus, when installed within the FTIR spectrometer, can determine the compositions of surface blooms, residues, and contaminants. An IR microscope can identify particles as small as 25 microns.
