This method is for determining benzene, individual hexanes and lower boiling hydrocarbons in olefin free naphthas having a final boiling point of 260癈 or lower. Results may be reported in mass-% or liquid volume (LV-%). The lower limit of detection for any single component is 0.01 mass-%.
C7 and heavier hydrocarbons are measured for calculation purposes, but are not reported by this method. For analysis of C7 and heavier hydrocarbons in addition to the C6 and lighter hydrocarbons, see ASTM Method D6729, "Determination of Individual Components in Spark Ignition Engine Fuels by 100 Metre Capillary High Resolution Gas Chromatography", UOP Method 690, "Octanes and Lower Boiling Hydrocarbons in Olefin Free Gasolines by GC", or UOP Method 880, "Hydrocarbon Types and Distributions in Low Olefin C12 and Lower Endpoint Distillates by GC".
