| Fourier transform infrared spectroscopy (FTIR)|
Fourier transform infrared spectroscopy (FTIR) is a technique which is 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.
The functional groups in organic compounds exhibit specific “finger print” absorption spectrum which can be used for material characterizations and ingredient identifications.
