Instrument
PerkinElmer Spectrum One model 2000.
Analysis target
Structural characterization of most materials (absorbing light in the infrared region) by comparison of fingerprint vibrations of reference compounds.
Sample prerequisites
All sample states of matter in principle possible, however, we don’t have a gas cell. Since the instrument is equipped with a ZnSe/diamond composite as the key component of the universal attenuated total reflection (ATR) sampling accessory literally no sample preparation is necessary (solids, pellets, powders, films, liquids are analyzed directly).
Analysis characteristics
FTIR is a vibrational spectroscopy that records absorptions of infrared light by chemical bonds in all molecules including polymers. Since different bonds absorb IR light at characteristic but different wavelengths FTIR spectroscopy is often referred to as fingerprint spectroscopy. As a consequence pure compounds have characteristic and unique FTIR spectra.
Sample requirements
A few mg depending on sample form.
