Oftentimes it becomes necessary to test sea water for oil and grease analytes. Whether it is due to a controlled release of effluent water from a waste water treatment plant (usually during large rain storms) or a large oil spill, there is a need generated for a reliable, automated extraction and evaporation system.

The purpose of this application note is to provide an in-line extraction and drying solution for measuring hexane extractable material (HEM) using solid-phase extraction. The extracts are dried in-line during extraction using ISOLUTE® Sodium Sulfate Drying Cartridges. Using the Speed-Vap®, the extracts are then concentrated with gentle heat and consistent air flow, and HEM concentration is determined gravimetrically.
