     These case studies show the performance using Sitelab’s UVF-3100D analyzer testing target polyaromatic hydrocarbons.  This includes the EPA's 16 PAH compounds. 

     When calibrated using Sitelab's PAH calibration kit (CAL-060) on the UVF's Slot D Optics, test results correlate well to U.S. EPA Method 8270 or similar laboratory methods using GC instrumentation.  This test can also be performed with GRO and EPH analysis to fingerprint the type or age of petroleum.   





Accuracy Testing PAHs in Soil

Examples of data generated by customers testing PAHs on various sites around the country:

  • Manufactured Gas Plant, Coal Tar Site

  • Power Plant, Coal Ash Site

  • Petroleum Tank Farm, Fuel Oil Site

  • Wharf Site with Heating Oil and Gasoline


See case study


Accuracy Testing PAHs in Asphalt

New regulations by the European Union require laboratory testing for polyaromatic hydrocarbons when recycling or disposing old tar and asphalt from road planings.  Sitelab's UVF-3100D and TD-500D analyzers are very sensitive to the same PAHs detected by the certified laboratory methods:

PAHs in Parking Lot Sealcoats

This 5 page Performance Study compares two types of parking lot sealcoats tested for polycylic aromatic hydrocarbons.  GuardTop, LLC manufactures asphalt based sealcoats and provided samples of their product and a popular brand of a coal tar product from another manufacturer.  Samples were analyzed by two certified laboratories using two PAH methods and by Sitelab using it's portable UVF instruments.

PAH Analysis in River Sediments

The Grand Calumet River is a tributary located in Northwest Indiana, which flows into Lake Michigan.  Sitelab Corporation was used to analyze 100 sediment samples collected from a post-dredge area covering a 1 mile stretch of river.     Maps were created using the field data showing the river's contamination.

Need to Test Benzo[a]Pyrene in Soil?

     A contractor performing work at a former military shooting range, sent samples to Sitelab to perform PAH analysis.  The soils were contaminated with lead shot and clay pigeons.  Clay pigeon targets are made with limestone mixed with petroleum asphalt pitch (often coal tar based), which contain high levels of Benzo[a]Pyrene and other PAH compounds as a result of the combustion process.

     Although Sitelab's UVF instruments cannot separately detect PAH compounds directly, response factors can be used to estimate and report Benzo[a]Pyrene or other problematic compounds accurately.  The samples tested during this pilot study were blind, well homogenized split samples previously tested by a certified lab using EPA Method 8270 by GC/MS. 

   Since the Sitelab Target PAH concentrations were close to the laboratory's total PAH concentrations, and the proportion of Benzo[a]Pyrene to the other PAHs was consistent, as reported by the lab, using a response factor to adjust the Sitelab results in order to estimate Benzo[a]Pyrene generated accurate and reliable data.  Sitelab's results can then be used on-site to help with soil removal, remediation and investigation efforts.
