Infrared (IR) spectroscopy

IR spectroscopy is used to record an IR spectrum of a material that is unique to that type of material, in other words a fingerprint of the material.

Measurements are carried out with a PerkinElmer Frontier FT-IR spectrometer.

IR spectroscopy can be used to identify an unknown organic material. Samples may vary from a small piece of a product (1x1cm), a powder (10mg), or even contaminants of up to 50 μm diameter. For this kind of identification, PTG/e has an extensive database of IR-spectra. IR analysis is also an excellent method for comparing different material batches as identical materials have an identical IR spectrum.
