Fourier Transform Infra-red Spectrometer (FT-IR)
- In infrared or IR spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through or transmitted. The resulting spectrum represents the molecular absorption transmission, creating a molecular fingerprint of the sample. Like a fingerprint, no two unique molecular structures produce the same infrared spectrum. This makes infrared spectroscopy useful for several types of analysis.
- Over 6000 spectrums to test against.
- FT-IR is preferred method of infrared spectroscopy today.
- Because each material is unique combination of atoms, not two compounds produce the exact same infrared spectrum
