UOP 501-83

This method is for determining aromatic, olefinic and saturated hydrocarbons in distillate fuels having viscosities in the range of 1.5 to 5.5 mm²/s (cSt) at 40 degrees C, boiling in the range of 150-400 degrees C (300-750 degrees F). Hydrocarbons boiling in the kerosine range are an exception and should be analyzed by ASTM D 1319 or UOP Method 311.

The indicated aromatic hydrocarbons include some diolefins and compounds containing sulfur, oxygen or nitrogen if these are present in the sample being analyzed.
