Selective Extraction of PCBs from Fish Tissue Using Accelerated Solvent Extraction
5 Feb 2014Selective 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.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
