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.

Case study - TPH Oil & Grease applications
These case studies illustrate the performance generated from customers who have used Sitelab’s UVF-3100 analyzer for testing total petroleum hydrocarbons in the C10 to C50 range.Sitelab’s TPH-Oil calibration kit is designed to correlate well to laboratory “Oil and Grease” test methods. This includes EPA Methods 1664 and 9071B by Gravimetric, EPA Method 418.1 by Infrared and others. Most regulatory agencies have now switched to TPH methods using Gas Chromatography (GC) instrumentation. For...
Case study - EPH in soil evaluation study at tank farm site
Ambient Engineering, Inc. (Concord, MA) used Sitelab to investigate and remediate a former tank farm along Boston Harbor contaminated by a large, subsurface plume of commingled diesel fuel and No. 6 fuel oil.Ambient’s Licensed Site Professional (LSP) had the opportunity – and budget – to evaluate Sitelab against three certified laboratories. Soil samples were collected from ten different locations having different depths and concentrations. Samples were analyzed using the Massachusetts DEP’s...
Case study - UVF and LIF used together at oil refinery site
A former oil refinery in Kansas has a 100-acre size plume of oil. The NAPL is commingled with gasoline, diesel, crude oil and other petroleum products. An environmental consultant used Sitelab’s UVF to field screen hundreds of soil samples for EPH C11-C22 aromatic hydrocarbons. Split samples sent to a confirmatory lab directly correlated (see graph).Laser Induced Fluorescence (LIF) had also been used on this site. LIF is sensitive to aromatic hydrocarbons, but results are qualitative (as % response). The...
Case study - Nigeria crude oil in soil site
Safic Technologies, Ltd. - Port HarcourtA pilot study was conducted testing soil samples collected from a pipeline spill. Split samples were sent to Sitelab for EDRO analysis and results were the same. Samples were also sent to a Nigerian lab and a highly reputable lab in the United States for confirmation. After testing the samples a second time, the American lab got better results. Labs from different countries report TPH in different carbon ranges.EDRO Calibration Kit Product No. CAL-042 Available in...
Case study - Texas crude oil in soil sites
Sunset Well Service, Inc. is an environmental contractor located in the Midland/Odessa area of Texas. They use their UVF-3100D analyzer to help excavate and remediate soils contaminated by produced water and crude oil. Laboratories in Texas test TPH using the TX 1005 GC-FID Method. This method is similar to U.S. EPA Method 8015M, but reports the GRO, DRO and ORO fractions separately.Soils from two spill sites were split and sent to a certified laboratory for confirmation analysis and the field results correlated...
