Fourier-Transform Infrared Spectroscopy (FTIR) is infrared spectroscopy that determines the molecular identity, functional groups and structure of a material. It identifies chemical bond by their characteristic absorption of infrared radiation in vibrational modes. It may be used in transmission mode or attenuated total reflectance (ATR) mode. FTIR is capable of identifying the chemical bonds of organic materials (solid, liquid or gas).
Thus, it can provide the following useful information:
- Identification of polymers and additives
- Determination of contaminants
- Quality control
- Qualitative oxidation determination in lubricants
- Material verification
- Comparative analysis
- Surface analysis
