Oil & Grease Testing
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.
Pacific® Sodium Sulfate Drying Cartridges offer
convenient in-line drying for Oil & Grease extracts prepared using Pacific® O&G extraction disks on the automated Biotage® Horizon 3100 Oil & Grease Extractor.
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.
