This method is for determining nitrogen in liquid hydrocarbons at concentrations ranging from 30 to 600 ng/g (mass-ppb). It is applicable to highly volatile samples, such as pentane, through the use of a cooled sampling system. Higher concentrations can be determined by ASTM Methods D4629, “Trace Nitrogen in Liquid Petroleum Hydrocarbons by Syringe/Inlet Oxidative Combustion and Chemiluminescence Detection,” D6069, “Trace Nitrogen in Aromatic Hydrocarbons by Oxidative Combustion and Reduced Pressure Chemiluminescence Detection,” and D7184, “Ultra Low Nitrogen in Aromatic Hydrocarbons by Oxidative Combustion and Reduced Pressure Chemiluminescence Detection,” using the cooled sampling system described herein for highly volatile matrices. Halogens and sulfur interfere at concentrations greater than approximately 1%.

This method is for determining the hydrogen content of light and middle distillates boiling in the range of approximately 15°C to 350°C on an as received basis, and hydrocarbons boiling above 350°C by dilution, using low resolution pulsed nuclear magnetic resonance (NMR). The range of quantitation is from 9.5 to 15.4 mass-% hydrogen. The concentration limits of the method may be extended if appropriate pure compounds are obtained as reference standards.

This method is for determining sulfur in liquid hydrocarbons at concentrations ranging from 10 to 1500 ng/g (mass-ppb). A direct measurement procedure (Part A) is used for samples above 100 ng/g. A trap & release procedure (Part B) is used for samples between 10 and 200 ng/g where high precision is required. This method is also applicable to highly volatile samples, such as pentane, through the use of a cooled sampling system.Higher concentrations can be determined by ASTM Method D5453, "Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence" and D7183, "Standard Test Method for Determination of Total Sulfur in Aromatic Hydrocarbons and Related Chemicals by Ultraviolet Fluorescence" using the cooled sampling system described herein for highly volatile matrices.
