  • Determination of PBDEs in Sediment Samples using Pressurized Solvent Extraction and Automated Soxhlet Extraction

    The efficiency of pressurized solvent extraction (PSE) was investigated by comparing PSE with automated Soxhlet extraction. Sediment samples containing polybrominated diphenylethers (PBDEs) were processed in the SpeedExtractor E-914 for PSE and the Extraction System B-811 for automated Soxhlet extraction. Quantification of PBDEs was performed by GC-MS. This study shows that both techniques are ...

  • Trace Analysis of PAHs using EPA methods 3541, 3545 and 8100

    The Extraction System B-811 and the Syncore Analyst parallel concentrator from Buchi as well as the Pressurized Solvent Extractor from Applied Separations were evaluated for the pretreatment of samples containing PAHs. Recoveries of extraction and subsequent concentration using acetone-n-hexane (1+1) were 70-95% for 2 ring and 90-100% for less volatile 3-5 ring PAHs. A good precision (95% ...
