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.

USP <467> Residual Solvents

Posted 10/1/2014 |

The USP general chapter <467> Residual Solvents is a method widely used for identifying and quantifying residual solvents when there is no information available on what solvents are likely to be present.  USP <467> is divided into two separate sections based upon sample solubility: water soluble and water insoluble articles.

As required by the analytical procedure given in USP <467> for identifying and quantifying residual solvents in drug substances, drug products and excipients, SPEX CertiPrep now offers 35 analytes in Dimethyl Sulfoxide for Class 1, Class 2 and Class 3 solvents.  Our products are manufactured and double checked by our QC department to validate the certificate of analysis which accompanies each product.

Residual solvents in pharmaceuticals are trace level impurities of volatile organic compounds in final products or excipients. In general, residual solvents originate from manufacturing processes related to the preparation of drug products. They can also form during product packaging and storage.
