Glossary entry:Total Petroleum Hydrocarbons
Meaning in EUGRIS: Equivalent Total Petroleum Hydrocarbons (E-TPH) is a summation of the Volatile Petroleum Hydrocarbons (VPH) value and the Extractable Petroleum Hydrocarbon (EPH). In order to avoid double counting of analytes due to the overlap in the carbon ranges existing between the two methods, the highest of the two values determined for the overlapping ranges is reported. [Volatile Petroleum Hydrocarbons (VPH) are defined as all hydrocarbon compounds eluting just prior to n-pentane through 1-methylnaphthalene. Extractable aliphatic hydrocarbons are collectively quantitated within five ranges: C8 through C10, >C10 through C12, >C12 through C16, >C16 through C21 and >C21 through C34. Extractable aromatic hydrocarbons are collectively quantitated within five ranges: C8 through C10, >C10 through C12, >C12 through C16, >C16 through C21 and >C21 through C34. These aliphatic and aromatic hydrocarbon ranges correspond to a boiling point range between approximately 150 C and 500 C.]
