FTIR is used to identify chemical substances. The coupling of liquid chromatography (LC)  with Fourier-Transform-Infrared (FTIR) spectroscopy allows the identification of unknown fractions with the help of a spectra database. When used in combination with a chromatographic system (GPC/SEC or HPLC), the substrate is collected on a rotating Germanium disk. FTIR-spectra can be gained for each point of the chromatogram. PSS uses a special interface to remove the solvent on-line after the chromatographic separation is done. This method allows for identification of the substance as well as for the evaluation of chemical heterogeneity.
