  • 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 ...

  • The Rapid Determination of PROXIMATE Nutrients in Foodstuffs by Fast-Scanning Mid-IR

    Measurement of basic nutritional components can be a time-consuming procedure with significant variances based on the skill of the analyst. The Standard Methods of Analysis of the AOAC define these tests and requirements in order to generate accurate and precise data. To analyze fat, samples are typically acid-hydrolyzed and then Soxhlet extracted with volatile solvents. However, similar data ...
