BRUKER FT-IR/FT-RAMAN SPECTROMETER
The IR spectroscopy can also be carried out by using Fourier transform technique. |
Description
The interference pattern obtained from a two beam interferometer as the path difference between the two beams is altered, when Fourier transformed, gives rise to the spectrum. The transformation of the interferogram into spectrum is carried out mathematically with a dedicated on-line computer.
The Bruker IFS66v FT-IR instrument consists of globar and mercury vapor lamp as sources, an interferometer chamber comprising of KBr and mylar beam splitters followed by a sample chamber and detector. Entire region of 10-10000 cm-1 is covered by this instrument. The spectrometer works under vacuum conditions. Solid samples are dispersed in KBr or polyethylene pellets depending on the region of interest. This instrument has a resolution of 0.1 cm-1. Signal averaging, signal enhancement, base line correction and other spectral manipulations are possible with multitasking OPUS software on the dedicated PC/AT 486. Spectra are plotted on a HP plotter and data can be printed or saved on a 3.5" floppy.
Sample required |
50 mg, solid or liquid. |
Applications :
Infrared spectrum is useful in identifying the functional groups like -OH, -CN, -CO, -CH, -NH2, etc. Also quantitative estimation is possible in certain cases for chemicals, pharmaceuticals, petroleum products, etc. Resins from industries, water and rubber samples can be analyzed. Blood and food materials can also be studied. Reaction mechanisms and concentration studies are done. For more information click here.>>>
