Abstract:

A high performance liquid chromatography-electrospray ionization-tandem mass spectrometric (HPLC-ESI-MS/MS) method was proposed for the determination of 11 perfluorinated compounds (PFCs) including 9 common PFCs, 2-perfluorooctyl ethanoic acid (FOEA) and 2H-Perfluoro-2-decenoic acid (FOUEA) in animal visceral (pork heart, pork liver, pork kidney, chicken heart and chicken liver) and muscle (pork tenderloin and chicken breast) tissues. WAX and MAX SPE cartridges were compared for the difference in recovery of 11 PFCs and WAX SPE cartridge was selected. Ion-pair liquid-liquid extraction and alkaline digestion were determined to be optimal methods for sample pretreatment of visceral and muscle tissues, respectively. In the determinations of real samples including pork liver, etc purchased from a local farmers market, the developed method exhibited low spike recoveries of PFTA, FOEA and FOUEA, while the spike recoveries of other 8 PFCs were found to be in the range of 80%-120%. The limit of detection of the method ranged from 0.002 to 0.032 ng/g.
