Nitrogen Speciation Analysis

Nitrogen Species Determination in Petroleum and Petrochemicals.

Intertek laboratories measure nitrogen species in petroleum, petroleum products from light-ends to gasoline and diesel fuels, petrochemicals and polymers. Nitrogen components detectable to trace levels. Analytical techniques used for nitrogen speciation analysis include chemiluminesence, GC/MS and GC/AED. Detection limits can reach 0.01 ppm.

• Carbazole
• 2-methyl Indole
• 3-methyl Indole
• Cyclohexylamine
• Quinoline
• Butyl Aniline
• Ethyl Aniline
