Persistent organic pollutants (POPs), such as polychlorinated dibenzo-p-dioxins (PCDDs), furans (PCDFs) and biphenyls (PCBs), continue to be analyzed all around the world in a wide variety of matrices, including environmental and food applications. The need for accurate, fast, and reliable sample extraction, cleanup and analysis has inspired both semi-automated and fully automated systems for the several steps in POPs sample processing.
A closed semi-automated cleanup system using a vacuum pump as the only mechanical part was developed with acidified silica, alumina, and carbon columns to oxidize the matrix structure and remove interferences. The sample cleanup process can be accomplished in 35 to 60 minutes depending on sample matrix, and is suitable for a wide range of matrices, including air, food, soil, sludge, and water samples. The system can be set up at low cost, and certified columns and the simple semi-automated system guarantee same day POPs analysis.
In this presentation we will discuss several cleanup methods with data and show how the Agilent 7010 GC-MS/MS instrument can be used for state-of-art dioxin and PCB work at levels of sensitivity equal to or better than magnetic sector instruments.

By attending this webinar you will learn:
- Semi-automated cleanup can greatly assist in fast and reliable sample processing for PCDD/Fs and PCBs measurements.
- The Agilent 7010 GC-MS/MS instrument can successfully carry out the analytical part of this process.
