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 measuringExample of Measurement in Near Infrared Region
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 measuringExample of Measurement in Far Infrared Region
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.
