Oil and grease analysis is routinely performed in many labs that also extract and analyze a variety of analyte suites using different EPA methods, so time management and flexibility are a necessity. The purpose of this application note is to optimize the solution for the removal and testing of total n-hexane extractable material (HEM).
This application note is compliant with the US EPA Method 1664B.
n-Hexane-extractable material (HEM), often termed oil & grease, is a 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, aliphatics, naphthenic and fatty acids.
In this application note, the measurement of the extracted material is done using a balance in regulatory methods US EPA 1664, ISO 11349 and Standard Methods 5520G, providing a simple and inexpensive detection step.
The first-class option for Hexane Extractable Material. Fast flow rates with dirty samples for excellent recovery and precision.
In-line drying of SPE elution solvents. Dry organic solvents with this easy to use format. Stack under SPE columns during elution for efficient, in-line solvent drying.
Easy way to incorporate the DryDisk® Separation Membrane into any laboratory setup.
Oil & Grease Extractor automates the entire extraction process and is fully compliant with US EPA Method 1664A/B and Standard Methods 5520G.
Three-position automated disk extraction system that conditions the disk, loads the sample (20 mL to 2 L) and elutes the analytes all without user intervention.
Automated solvent evaporation system that provides safe and fast evaporation of solvent for Oil and Grease extractions.
Have you ever been extracting samples for oil and grease compounds using solid phase extraction (SPE) and thought, “why do I have to use all these different solvents, when I’m just trying to get my compounds to retain on, and then elute from, an SPE disk?”
How to streamline analysis, meet regulations and achieve laboratory compliance with solid-phase extraction.
Automated sample preparation reduces errors, improves method robustness and frees up laboratory personnel for other tasks.
Biotage evaporation systems are designed for fast solvent evaporation and minimizing sample transfer.
