UOP 971 – Trace Nitrogen in Light Aromatic Hydrocarbons by Chemiluminescence
This method is for determining total nitrogen in light aromatic hydrocarbons, such as benzene. It is applicable to quantitative determination of nitrogen at a level of 30 to 400 ng/g. Samples containing more than 400 ng/g nitrogen can be analyzed according to ASTM D 4629 or D 6069. Halogen and sulfur-containing compounds can interfere if any one or all of these elements are present in a sample in concentration greater than 10%.
