- Total petroleum hydrocarbon
Total petroleum hydrocarbon (TPH) is a term used to denote a large family of several hundred
chemical compounds that originally come from crude oil. Crude oil is used to make petroleumproducts which can contaminatethe environment. Because there are so many different chemicals in crude oil and in other petroleum products, it is not practical to measure each one separately. However, it is useful to measure the total amount of TPH at a site. Some chemicals that may be found in TPH are hexane, jet fuels, mineral oils, benzene, toluene, xylenes, naphthalene, and fluorene, as well as other petroleum products and gasolinecomponents. However, it is likely that samples of TPH will contain only some, or a mixture, of these chemicals.

Various methods to analyze the components of TPH are introduced in a Nordic report [Use of Ozone Depleting Substances in Laboratories. TemaNord 516/2003. [http://www.norden.org/pub/ebook/2003-516.pdf] ] . The report evaluates critically various new methods replacing the old ones using banned ozone depleting substances.
