HPLC is a chromatographic separation method that can be used to separate chemical substances as well as to identify, quantify and purify them using specific standards. The analyzed sample is pumped with a running medium (mobile phase) over a stationary phase in a separation column (2-30cm length, Ø2-5mm). Depending on the two phases, the components of a mixture of substances interact differently with the stationary phase and are thus eluted at different retention times. Depending on the type of the sample, detection is performed by UV/VIS detector, fluorescence detector, diode array detector (DAD) or light scattering detector. The velocity is determined by the re-dissolution into the mobile phase. There are two distinct methods: normal phase HPLC (NP) with polar stationary phase (e.g. silica gel) and non-polar mobile phase, where polar molecules are retained on the column, and reversed phase HPLC (RP). While using non-polar stationary phase (silanes, substituted with non-polar long-chain hydrocarbons, e.g. C18), the elution strength decreases with increasing polarity.

A chemical compound can only be identified to a limited extent by HPLC by comparing the retention time of the unknown substance with that of a defined reference compound (external standard method) or by following mass spectroscopic (MS) analysis.


  • Organic compounds e.g. proteins, vitamins, sugars, ingredients of cosmetic formulas


  • Analysis and chemical purification of soluble pollutants (e.g. those adhering to particulate matter) as well as protecting active compounds (e.g. antioxidants)
