Concentrating PCB Congeners 10 Thousand Fold with the Horizon Technology DryVap® Concentration System
4 Sept 2016Polychlorinated biphenyls (PCBs) are found throughout the environment and are recognized as a serious health threat. They accumulate in animals and plants and become more concentrated as they progress up the food chain. This application note presents an experiment focused on the recovery levels of PCB congeners after concentrating spiked solutions 10 thousandfold with the DryVap® concentrator system.
