Molecular fingerprint

Infrared spectroscopy is used to identify an unknown material by recording a fingerprint. The technique distinguishes the different functional groups within a molecule. Samples may vary from a small piece of a product (1 x 1 cm), to a powder (10 mg), or even contaminants of down to 500 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, since identical materials have an identical molecular fingerprint.

IR infrared spectroscopy is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms.
