Fourier Transform Infrared Spectroscopy relies on the fact that the most molecules absorb light in the infra-red region of the electromagnetic spectrum. This absorption corresponds specifically to the bonds present in the molecule. The frequency range are measured as wave numbers typically over the range 4000 – 600 cm-1. It is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. This simultaneously collects high-spectral-resolution data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time.
Fourier Transform infrared spectroscopy (FTIR spectroscopy) covers a wide range of chemical applications, especially for polymers and organic compounds for examples paints, adhesives, resins, polymers, coatings and drugs. It is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range.
- Keep the instrument dry. Avoid spilling liquid onto the instrument. Clean all external spills immediately.
- Do not use a flammable gas to purge the instrument. The instrument contains a hot source, and a fire or explosion will result.
- Only plug the instrument power supply into a socket power outlet that is provided with a protective earth connection.
