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.
