VPH Analysis and EPH Analysis

06 Jan VPH Analysis and EPH Analysis

Assessing the Impact of Petroleum Hydrocarbons

The release of petroleum products into the environment is a known cause of contamination. VPH Analysis and EPH Analysis are gas chromatography methods that are used to determine the toxicology of petroleum sites.

Created by the Massachusetts Department of Environmental Protection (MA DEP), VPH Analysis and EPH Analysis offers greater insight into the effects of petroleum contamination on the environment and the specific hydrocarbon composition of the contaminant.

Perhaps the greatest benefit of using VPH Analysis and EPH Analysis is these methods allow for greater risk management with regard to clean-up. The results of VPH Analysis and EPH Analysis enable petroleum clean-ups to be planned in relation to the risk of the substances that are present.

 

VPH Analysis (Volatile Petroleum Hydrocarbon)

The VPH analysis method is used for the quantification of individuals fractions of aromatic and aliphatic hydrocarbons in soil, water or sediment, based on the quantity of carbon atoms in the constituent compounds.

The VPH analysis method quantifies volatile aliphatic hydrocarbons within two ranges:

C5 – C8

C9 – C12

VPH Analysis is suitable for evaluating certain petroleum naphthas, mineral spirits and petrol / oil.

Its target analytes are Toluene, Benzene, Ethylbenzene, Xylenes (BTEX) Napthalele and Methyl-tert-butylether (MTBE).

 

EPH Analysis (Extractable Petroleum Hydrocarbon)

 

The EPH analysis method quantifies individual fractions of extractable hydrocarbons in sediments, water and soil, according to the number of carbon atoms in the constituent compounds.

The EPH analysis method quantifies extractable aliphatic hydrocarbons within these two ranges:

C9 – C18

C19 – C36

EPH Analysis is suitable for evaluating jet fuels, diesel fuels and petroleum-based lubricant oils. The targets are polyaromatic hydrocarbon (PAH) analytes and diesel PAH analytes.
