Determination of Nitrogen in Light Aromatic Hydrocarbons by Oxidative Combustion with Chemiluminescence Detection

For the analysis of ultra-trace levels of total nitrogen (TN) in these sample types it requires very precise and reliable sample introduction and combustion process design in order to avoid any interference or analyzer downtime caused by incomplete combustion. The EST NEXIS , Total Nitrogen Analyzer, equipped with the uniquely designed NEX-Z combustion tube ensures an optimum conversion from organic bounded nitrogen present in the sample to the nitrogen oxide product.
