PAH testing is used to identify polynuclear and polycyclic aromatic hydrocarbons, which are fused aromatic rings starting with naphthalene C10H8 which increase in molecular weight. PAH compounds may also be made up, including five membered rings as in Benzo(j)fluoranthene. Because many of these compounds are known carcinogens, industry standards and government regulations heavily curb their use in consumer products. To keep our manufacturing clients compliant with these rules, Applied Technical Services performs PAH testing on sample materials.
What are They Commonly Found In?
Polynuclear aromatic hydrocarbons (PAHs) — “PAHs often are byproducts of petroleum processing or combustion. Many of these compounds are highly carcinogenic at relatively low levels.” — Eaton and others, 2005

What Instrumentation Does ATS Use for PAH Testing?
ATS utilizes Gas Chromatography / Mass Spectrometry (GC/MS) with a current detection limit of 100 parts per billion (ppb) for PAH testing.
