The Biotage® VacMaster™ Disk is a unit for performing manual, disk-based extractions designed for high productivity laboratories. This unit is an excellent first step for labs interested in moving from liquid-liquid extraction (LLE) to solid phase extraction (SPE) for sample preparation in the environmental, food and beverage, and agriculture industries.

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.

This application note describes the use of the Biotage® VacMaster™ Disk to extract n-hexane-extractable materials (HEM) from wastewaters per EPA Method 1664B. The procedure outlined in this document was used to generate a minimum level of quantitation (ML) and an initial demonstration of capability (IDC). Data for those studies is presented here.
