New regulations by the European Union require laboratory testing for polyaromatic hydrocarbons (PAHs) when recycling or disposing old tar or asphalt from road planings. 

Sitelab’s portable UVF-3100D and TD-500D analyzers have similar sensitivity to these types of compounds. The equipment is easy to operate and samples can be tested in the field in less than five minutes. A 5 gram sample is extracted in solvent using disposable test kits and then measured on the instrument which is calibrated using Sitelab’s PAH calibration kit. Results will directly correlate to certified laboratories using GC/MS methods.

Sitelab’s analyzers cannot detect one compound from another, but response factors are commonly used to estimate Benzo[a]Pyrene (BAP) or other PAH compounds of concern.
