IP 379: Determination of organically bound trace nitrogen — Oxidative combustion and chemiluminescence method

Overview:

Scope

This test method covers the determination of the trace total nitrogen naturally found in liquid hydrocarbons boiling in the range from approximately 50 °C to 400 °C, with viscosities between approximately 0.2 and 10cSt (mm²/s) at room temperature. This test method is applicable to naphthas, distillates, and oils containing 0.3 to 100 mg/kg total nitrogen.
