ASTM D7184Standard Test Method for Ultra Low Nitrogen in Aromatic Hydrocarbons by Oxidative Combustion and Reduced Pressure Chemiluminescence
ASTM D7184用氧化燃烧和减压化学发光法测定芳烃中超低氮的试验方法
This test method is useful to detect and quantify nitrogen-containing compounds at a concentration of 0.03 to 1 mg N/kg in light aromatic hydrocarbons used or produced in manufacturing process. These nitrogen-containing compounds are undesirable in finished aromatic products and may be used i
