WebEPA Method 8310: Solid Phase of Polynuclear Aromatic Hydrocarbons (PAHs) in Water Summary: Polynuclear aromatic hydrocarbons (PAHs) are consisted of a large group of organic compounds with two or more fused aromatic rings. Hundreds of different PAHs may be generated from incomplete combustion or pyrolysis of organic materials, smoked or Webconditions for the detection of ppb levels of certain polynuclear aromatic hydrocarbons. Prior to use of this method, appropriate sample extraction techniques must be used. A 5- to 25-uL aliquot of the extract is injected into an HPLC, and compounds in the effluent are detected by ultraviolet (UV) and fluorescence detectors. how do they train bucking horses
