Automated Pressurized Liquid Extraction and Sample Clean Up of River Sediment in POPs Analysis

摘要

As can be seen the sediment analysis showed excellent agreement between the values found with our automated extraction and clean up and the acceptable reference values provided for this material. Furthermore, the method gave excellent recoveries. Extraction, clean up and analysis by properly trained personnel can be carried out in one day, resulting in low turnaround times for large (and small) sample batches.
