Polychlorinated Biphenyls (PCB) are a worldwide contamination problem. They are extremely stable and as such, very long lived in the environment. The end result is that PCBs tend to bioaccumulate throughout the food chain and a great deal of research and regulations have been dedicated to their study.

EPA Method 608 describes the procedure to determine low parts per billion levels of organochlorine pesticides, polychlorinated biphenyls, toxaphene and chlordane in wastewater. The laboratory that collected the data presented in this application note uses EPA method 608 ATP3M0222 as the approved SPE technique for waste water extraction.
The disks compared in this study are : “Certified for Automation” Atlantic™ C18 (47 mm) and 3M Empore™ High Performance Extraction Disk C18 (47 mm). Comparisons were made using side-by-side extraction and identical calibration parameters.

The City of Fort Worth, Water Department conducted an evaluation of the Atlantic™ solid phase extraction (SPE) C18 disks using EPA Method 608. This application note describes the procedure to determine low ppb levels of organochlorine pesticides and PCBs in wastewater. This procedure used methylene chloride as the primary extraction solvent, followed by a hexane solvent exchange. Extracts were then analyzed by GC/ECD using a pressure pulse injection technique.
