Summary
This standard specifies the method for determining the type and content of nitrogen compounds in middle distillate oil by using gas chromatography-nitrogen chemiluminescence detection method (GC-NCD). This standard is applicable to middle distillate oils such as catalytically cracked diesel, straight-run diesel, hydrocracked diesel, etc., with a boiling point range of 180�桫380�� under normal pressure, and the mass fraction of total nitrogen is 20mg/kg��1000mg/kg (using SH /T 0657 or NB/SH/T 0704). The measurement range of nitrogen mass fraction of monomer nitrogen compounds is 1mg/kg��130mg/kg, the measurement range of total neutral nitrogen compounds nitrogen mass fraction is l0mg/kg��800mg/kg, the measurement range of total basic nitrogen compounds nitrogen mass fraction 10mg/kg��350mg/
