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.

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.

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.

Hexane extractable material (HEM), also known as Oil & Grease extraction is a simple water quality measurement. The measurement can be used to assess pollution for compliance or as a measure of influent contamination to protect a waste treatment plant from levels that might cause malfunction.
Part No: AN942Issued year: 2020File size: 1.63mbFile type: pdf
The purpose of this application note is to optimize the solution for the removal and testing of total n-hexane extractable material (HEM) using solid phase extraction in combination with the Biotage® Horizon 5000 automated extraction system.
Part No: AN102-HOR.V.2Issued year: 2016File size: 1.49mbFile type: pdf
n-Hexane-extractable material (HEM), often termed oil & grease, is an operationally-defined general measurement used around the world to help assess water pollution due to a variety of hydrocarbons, including dissolved aromatics, benzene, toluene, xylene and dispersed polynuclear aromatic hydrocarbons (PAHs), aliphatics, naphthenic and fatty acids.1
