Epub 2012 Sep 11.The main objective of this work is to develop an accurate, sensitive, simple and cost-effective method for the determination of tributyltin species (as cationic form) in seawater at ultra-trace levels. The method is based on the use of stir bar sorptive extraction (SBSE) followed by solvent desorption and liquid chromatography tandem mass spectrometry (SD-LC-MS/MS (QqQ)) analysis, operating in positive electrospray ionisation (ESI) and in the selected reaction monitoring (SRM) mode.
