ASTM D6069:

ASTM D6069 is the Standard Test Method for Trace Nitrogen in Aromatic Hydrocarbons by Oxidative Combustion and Reduced Pressure Chemiluminescence Detection

This test method is withdrawn in 2015 but covers the determination of Total Nitrogen (organic and inorganic) in aromatic hydrocarbons, their derivatives and related chemicals. ASTM D6069 is applicable for samples containing nitrogen from 0.2 to 2 mgN/kg, but has been replaced by Test Method ASTM D7184. For higher Nitrogen concentrations refer to Test Method ASTM D4629.

To comply with ASTM D6069, TSHR offers NEXIS TN, NEXIS VP TN and TN 6000/7000 series models and combined instrument configurations like TN/TS models with semi-automatic syringe or fully automatic liquids injection through AS120 and HR 7000 models Liquids Autosampler configurations for this ultra trace level Total Nitrogen analysis.
