Measures from Near Infrared to Far Infrared
By simply exchanging the light source, beam splitter, and detector, the IRPrestige-21 not only measures in the usual mid-infrared region, but also measures in the near infrared and far infrared regions as well. This provides the following benefits.
|Benefits of Near Infrared Measurement||Benefits of Far Infrared Measurement|
|Samples can be left in glass or plastic containers for measurement
Measures without dilution by KBr or other substance
Allows observing overtone and combinations of peaks in the mid-infrared region
|Allows observing absorption peaks from oxides of inorganic elements
Allows observing absorption peaks from halogen compounds
Example of Measurement in Near Infrared Region
The figure to the right shows an example of measuring amino acids (upper: L-alanine, middle: L-glutamic acid, and lower: L-arginine) with optional accessories attached for near infrared measurement.
In this example, a high-sensitivity InGaAs detector was used as the detector for the near infrared region. This allows obtaining high quality spectra in the near infrared region without diluting the sample with KBr or other substances.
Example of Measurement in Far Infrared Region
The figure to the right shows an example of measuring Ba2O3 with optional accessories attached for far infrared measurement. Using a CsI beam splitter allows obtaining high quality spectra even at wavelengths below 400 cm-1, which is useful for confirming absorption peaks of inorganic compounds and organic metal complexes.
