At elevated temperatures mineral oil based lubricants are prone to oxidation. Thus, antioxidative stabilization of engine oils is an important issue in lubrication engineering. Although there are various tests in order to assess the oxidative stability of a lubricant, only very little is known about the depletion process of antioxidants on a molecular level. The current study presents a solid-phase extraction method capable of isolating antioxidants and corresponding degradation products from engine oils as well as a high performance liquid chromatography (HPLC) method for their subsequent separation. For detection the HPLC system was coupled to a UV detector and a high resolution quadrupole time-of-flight mass spectrometer (QTOF-MS). These...
