Automated Sample Cleanup with DEXTech: A Simple and Cost-Effective Solution for the Determination of POPs in a Wide Variety of Matrices

In this session, we present an overview of the automated DEXTech Cleanup system, which offers a practical and affordable solution for detecting dioxins/furans, 209 PCB or PCNs, CPs, and PBDEs.

The importance of enhancing laboratory setups to monitor persistent organic pollutants (POPs) is emphasized, particularly in light of incidents like the East Palestine, Ohio train accident. The DEXTech Cleanup system provides several advantages, including rapid turnaround time for results, suitability for processing high sample volumes, reduced manpower requirements, and affordability.

Three versions of the system will be presented: a standard unit without heating, a heated version, and an automated system capable of processing 15 samples. Data is presented for various POPs analysis methods, such as US-EPA Method 1668C for 209 PCBs, US-EPA Method 1613 for 2,3,7,8 substituted PCDD/Fs, and Commission Regulation (EU) 2017/644 for dioxin-like PCBs and indicator PCBs.
