PYE [2-(1-pyrenyl)ethyldimethylsilylated silica] Column HPLC and HR-GC-(micro) ECD in the Accurate Determination of Toxic Co-planar PCBs and Polybrominated Diphenyl Ethers (PBDEs)

170, 180 andpolybrominated diphenyl ethers (PBDEs) such as 47, 66 , 85, 99, 100, 138, 153, 154 in environmental samplesbecome almost mandatory in several countries now. Howe ver, most of the available methods involve expensiveinstrumentations such as HRGC-HRMS or ECNI-LRMS, apart from expensive extraction and clean-up (withlarge volume of solvents) steps. A method has been de vised combining the analytical separation power of PYE[2-(1-pyrenyl)ethyldimethysilylated silica] column HP LC and high-resolution gas chromatographic techniquesincluding micro-electron capture detection (ECD) and two dimensional gas chroma tograpy-ECD techniques todetermine these eco-toxic substances at parts-per-trillion (ppt) levels. This combination resolves co-elution ofcongeners that occur in disproportionate ratios (
