Ana Reis from the Mass Spectrometry Center, UI-QOPNA, Chemistry Department, University of Aveiro, Aveiro, Portugal answers questions on her research into structural motifs in primary oxidation products of palmitoyl-arachidonoyl-phosphatidylcholines by LC-MS/MS.
Development of a Rapid Liquid Chromatography Tandem Mass Spectrometry Method for Determination of Trace Caffeine in Surface Water
A rapid LC/MS/MS method for the quantification of caffeine in surface water samples is presented. This method employs large volume injection on a single LC reversed-phase column with detection in ESI positive mode. The method is robust and has the advantage of requiring no extensive sample preparation steps.
