The Analysis of Persistent Organic Pollutants Using Pressurized Liquid Extraction and Automated Column Chromatography Sample Cleanup

Persistent organic pollutants (POPs) such as polychlorinated dibenzop-dioxins (PCDDs), furans (PCDFs), biphenyls (PCBs), polybrominated diphenylethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) continue to be analyzed around the world. Their persistent nature and toxicity lead to high dema...

Description
Summary:Persistent organic pollutants (POPs) such as polychlorinated dibenzop-dioxins (PCDDs), furans (PCDFs), biphenyls (PCBs), polybrominated diphenylethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) continue to be analyzed around the world. Their persistent nature and toxicity lead to high demands for quick and accurate sample analysis. This article describes the use of automated sample processing techniques such as pressurized liquid extraction (PLE) and automated column chromatography cleanup that are found to be very suitable for environmental sample analysis. Excellent recoveries, reproducible results, quick turnaround times with sameday results, and closed-loop systems with low background and low power use make the techniques suitable for both academic and commercial production environments. Examples of the analysis of sediment (certified reference material) and soil are given.
