Vibrational spectrometry describes the vibrations of molecules and parts of molecules in an analyte. The result of the measurement is usually a vibrational spectrum. Vibrational spectrometry can be used to identify or characterize substances present in a sample or to predict the structure of the molecules of the substances under investigation. It can also be used to identify unknown substances or detect contaminants or impurities in the sample. Vibrational spectroscopy is not a trace analysis method (it can detect substances with a content greater than 0.1 %). Vibrational spectroscopy is not intended for elemental analysis (determination of elements in the sample). Vibrational spectroscopy can analyse a wide range of different types of samples. In our Vibrational Spectrometry Laboratory, we mainly analyse solids; however, analysis of liquids and gases is also possible. A sample quantity of approximately 10 mg is sufficient for the analysis of solids. The quantity required to analyse liquid or gaseous samples must be consulted in advance.
