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.

Method 525.2 describes the procedure to determine a full suite of low concentration semi-volatile organic compounds in drinking water using solid phase extraction (SPE) or liquid–solid extraction (LSE) techniques. The City of Fort Worth, Water Department implemented an automated SPE process for the analysis of semi-volatiles by EPA Method 525.2 using the Atlantic® C18 solid phase extraction disk. Ethyl acetate, methanol and water were used to condition the Atlantic C18 disk prior to the extraction step. The extraction solvents used were a 1:1 mixture of methylene chloride and ethyl acetate. Extracts were then analyzed by GC/MS using a splitless injection technique.

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.
