NJDEP Extractable Petroleum Hydrocarbon Method

Posted 12/11/2014 |

SPEX CertiPrep is pleased to announce that we now offer NJDEP EPH (Extractable Petroleum Hydrocarbon) Method standards. The NJDEP developed this EPH method to comply with health-based criteria for site remediation efforts, and includes procedures to separate the petroleum content into specific carbon ranges.

This method utilizes a gas chromatograph (GC) fitted with a flame ionization detector (FID) to determine the collective concentrations of extractable aliphatic and aromatic petroleum hydrocarbons in water and soil/sediment matrices.

This method can be used for the quantitative analysis of environmental samples (water, soil, sediment, and sludge) and for residues from commercial petroleum products such as crude oil, diesel fuel, waste oil, fuel oil, lubricating oil, processed oil and bunker fuel.
