The objective for this research was to provide a high throughput extraction, while improving the quality and consistency of results with half the solvent usage than in a conventional 8270D liquid liquid extraction (LLE) or continuous liquid liquid extraction (CLLE). Method 8270D has a very extensive list of semi volatile organic compounds that range in volatility. The SPE-DEX® 4790 solid phase extraction (SPE) instrument would be paired along with a hydrophilic-lipophilic balanced (HLB) SPE disk necessary to retain the wide range of compounds in this method. The addition of a Carbon Cartridge was needed in order to retain the more volatile compounds. In our research for the more volatile compounds we were able to achieve recoveries from 44%-84%. With a full list 8270 we are able to achieve results ranging from 34%-95%.
