Method AK101 is designed to measure the concentration of Gasoline Range Organics (GRO) in water and soil. This corresponds to an n-alkane range from the peak start (C6) to the peak start of (C10) and to a boiling point range between approximately 60? C and 170? C. This range is also known as Volatile Petroleum Hydrocarbons (VPH) in some states.
