The separation of 52 Polycyclic Aromatic Hydrocarbons including the low volatility dibenzopyrenes was performed on a specifically designed Thermo Scientific TraceGOLD TG-PAH GC column
Accelerated solvent extraction is an innovative sample preparation technique that combines elevated temperatures and pressures with liquid solvents to achieve fast and efficient removal of analytes of interest from various matrices. Accelerated solvent extraction has been demonstrated to be equivalent to existing extraction methodologies such as Soxhlet and automated Soxhlet for most RCRA (Resource Conservation and Recovery Act) analytes from solid and semisolid samples. It meets the requirements of U.S. EPA Method 3545, Pressurized Fluid Extraction.
The procedures described in this application note meet the requirements for sample extraction as determined by U.S. EPA Method 3545. This method is applicable to the extraction of water-insoluble or slightly water-soluble volatile and semivolatile compounds in preparation for gas chromatographic or GC/MS measurement. This method is applicable to soils, clays, wastes, and sediments containing 250–12,500 μg/kg of BNA compounds.
This method describes an on-line SPE HPLC method with UV absorbance and fluorescence detections for rapid and sensitive determination of 20 PAHs in tap water. The determination is performed on a Thermo Scientific UltiMate 3000 Dual RSLC system combined with a Thermo Scientific Hypersil Green PAH analytical column. Reduced MDLs for UV and fluorescence detection, enabled by on-line SPE using the Thermo Scientific Dionex Acclaim PA2 column, provide a convenient method for determining these compounds in drinking and environmental waters using HPLC.
