Extractable Petroleum Hydrocarbon (EPH) – Extractable Background of Resprep EPH Cartridges

Restek’s Resprep EPH Fractionation SPE Cartridges (cat # 25859) provide method-specific performance for EPH analysis of soil and water samples through complete separation of aliphatic and aromatic compounds into distinct fractions, while providing extractable background levels guaranteed to fall under the strict reporting limits of Massachusetts and New Jersey EPH methods.   The cleanliness of […]

Extractable Petroleum Hydrocarbons (EPH) – Lot to Lot Reproducibility of Resprep EPH Cartridges

As previously discussed in my last blog, “Extractable Petroleum Hydrocarbons (EPH) Method – Why it is important?”, Restek’s Resprep EPH Fractionation SPE Cartridges (cat # 25859) provide method-specific performance for EPH analysis of soil and water samples through complete separation of aliphatic and aromatic compounds into distinct fractions, while providing extractable background levels guaranteed to […]

Extractable Petroleum Hydrocarbons (EPH) Method – Why it is important?

Spills and releases of petroleum fuels are the largest source of environmental contamination in the United States. Massachusetts published a method that addresses the need to account for semi-volatile aliphatic and aromatic fractions of gasoline using gas chromatography (GC) analysis and a flame ionization detector (FID). This method was designed to measure the collective concentrations […]
