Detection of Total Nitrogen in Biodiesel and High Grade Chemicals - ASTM D4629

ASTM D4629 covers the determination of total Nitrogen in concentrations ranging from about 0,3 to 100 mg/kg in liquid petroleum products having a boiling point range of 50˚C to 400˚C and viscosities between 0,2 and 10 mm²/s at ambient temperature.

The ASTM D4629 standard is the preferred method in many countries to detect and quantify total bounded nitrogen containing compounds in the various type of automotive fuels such as blended gasolines, diesel and synthetic oils.
Nitrogen compounds can have detrimental effects on many environmental and industrial processes and are undesirable in finished products. This supports the need and importance to monitor trace level nitrogen concentration of various type of automotive fuels and related products.
