Application Note: Selective Extraction of PCBs from Fish Tissue Using Accelerated Solvent Extraction
5 February 2014

Selective extraction procedures have been developed using the accelerated solvent extraction technique (ASE). The recovery of polychlorinated biphenyl (PCBs) from contaminated fish tissue was investigated and showed that extracts do not require further cleanup prior to analysis by gas chromatography buffer, an ion-pairing agent, and acids such as ethylenediaminetetraacetic acid (EDTA)— all essential for good peak shape but detrimental to mass spectrometry—when using accelerated solvent extraction.
