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.

US EPA Method 1664 for Hexane Extractable Material (HEM) or Oil and Grease has allowed use of solid phase extraction (SPE) instead of liquid-liquid extraction (LLE) with hexane since 2007 and this has been widely adopted in the US. SPE is an equivalent extraction technique to LLE and produces the same n-hexane extract. The extract, similar to LLE, may contain residual water that must be treated properly and removed from the n-hexane extract.
