Infrared spectroscopy is a simple, reliable analytical technique for organic materials. FT-IR instrument relies upon interference of various frequencies of light to collect a spectrum. The spectrometer consists of a source, beamsplitter, two mirrors, a laser and a detector; the beamsplitter and mirrors are collectively called the interferometer. The IR light from the source strikes the beamsplitter, which produces two beams of roughly the same intensity. One beam strikes a fixed mirror and returns, while the second strikes a moving mirror. A laser parallels the IR light, and also goes through the interferometer. The moving mirror oscillates at a constant velocity, timed using the laser frequency. The two beams are reflected from the mirrors and are recombined at the beamsplitter. The transmitted portion reaches the detector, which records the total intensity. The raw detector response yields an interferogram.




  • Sample should be submitted in solution or powder form
  • Generally 5 ml of solution is sufficient for analysis
  • Solvents such as alcohol or acetone is more preferable for diluting the sample
  • Explosive, poisonous s and toxic gases or fumes cannot be undertaken FTIR analysis. Moisture content is not acceptable in FTIR analysis because of KBr crystal.
