This study shows that the SPE-DEX® 4790 Automated Extractor system can process water samples containing suspended particulate matter, up to 1000 mg, for the analysis of PAH’s. As PAH’s are found in both the dissolved and particulate phase of the water sample, it is important to be able to handle “whole” water samples such that the particulate matter in the water sample is retained and extracted with the SPE disk. This filtration method ensures that the PAH’s found in the dissolved phase, and those adsorbed onto the particulate matter are properly

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.

This technical note describes the use of layered SPE columns in applications where multiple suites of analytes with a broad polarity range are to be extracted simultaneously from a single water sample, such as organochlorine, triazine and organophosphate pesticides, or endocrine disrupters.
