Example text

A blank and a reference sample must be included in each test series, which is extracted and tested at the same time under identical conditions. The reference sample must show a clearly elevated response in comparison to a blank. Gas chromatographic analysis Gas chromatography has always been the method of choice for the determination of PCBs due to the volatility and the complexity involved in separating the isomers of these molecules (de Boer 1999). PCBs are present in a complex mixture of congeners, ranging from monohalogenated to heavily halogenated compounds (Santos and Galceran 2002).

The combination of high pressure and 27 temperature allows rapid extraction with little solvent consumption but requires the use of very expensive and specialized equipment (Liem 1999b; Carro et al. 2002; Björklund et al. 2006; Mendiola et al. 2007; Beyer and Biziuk 2008). Compressed gas is then used to purge the sample extract from the cell to the collection vessel (Richter et al. 1996). PCB analysis in oyster tissues has been done using isooctane (Richter et al. 1996) and pentane (Gómez-Ariza et al.

2002; Fidalgo-Used et al. 2007). For fish homogenate samples, optimal PCB extraction recoveries were observed in the temperature range of 90°– 120°C. The combination of high pressure and 27 temperature allows rapid extraction with little solvent consumption but requires the use of very expensive and specialized equipment (Liem 1999b; Carro et al. 2002; Björklund et al. 2006; Mendiola et al. 2007; Beyer and Biziuk 2008).
