Total petroleum hydrocarbons (TPH) are a family of several hundred chemical compounds made from crude oil. TPH are found in soils and water. Exposure to TPH can affect human health and, therefore many laboratories around the world are analyzing TPH levels in the environment. This application note describes the extraction of TPH from soil, sediment, and waste samples using the SpeedExtractor E-916. The determination of TPH was done by GC-FID. The results show that the SpeedExtractor delivered reliable results with good recoveries. The extraction used 70 ml of solvent per replicate and required only 30 min.
