Fourier Transformation Infrared Spectroscopy or for short; FTIR uses light in the infrared spectrum to analyse a sample. The sample absorbs IR light at frequencies corresponding with the present bond types. After a fourier transformation an IR spectrum is the result and is run through a database which is able to recognize a best fit. Also manual interpretation of the spectra is possible when requested. Please note that this method is not suitable for quantitative determinations and is only useful for qualitative purposes. Any component present in concentrations lower than approximately 5% is not detectable using this method.
The apparatus features a golden gate so no KBr tablet has to be made.
