Definition of petroleum hydrocarbons all aromatic hydrocarbons) ➢diesel range organics (dro): c8 – c30 (aliphatic and aromatic hydrocarbons including the 16 epa pahs) ➢extended diesel range organics (edro): c10 – c40 (contains some of the lubricating determination of the target compounds but none. Several hundred chemical compounds that originate from crude oil (mainly hydrogen and carbon) because tph can be divided into groups (fractions) of petroleum hydrocarbons that act alike, it is not practical to measure each chemical separately rather, the total tph should be measured in order to identify the mixture.

Gas chromatography for identification of petroleum products gc remains the most widely used technique to identify petroleum products in the environment • most fuels and lubricants are too complex to allow full speciation of every component identification/quantification of target components visual inspection and target. Because of the extreme complexity of the composition of petroleum and petroleum-related products, no single analytical method can be used to identify all of its important components in environmental samples moreover, because petroleum is a labile mixture, the composition of a product released into the environment.
In this work we discuss the influence of these parameters on the results, and what challenges the determination of petroleum hydrocarbons in water poses in general the inadequacy of the two methods to provide a full equivalent to the earlier 'total petroleum hydrocarbon' (tph) method is highlighted using a number of.
