ASTM D5453:
ASTM D5453 is the Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence
The Total Sulfur content in automotive fuels is a key parameter when undertaking process/quality control analyses and for ensuring compositional specifications in finished refinery products are met. Sulfur components in process feeds may damage the catalyst performance in refinery processes, so lowering the refinery efficiency and profitability. Additionally, the Total Sulfur content in products like automotive fuels is subjected to restrictions by regional and international regulations, such as the Tier 3 program, and must therefore be monitored using reliable methods and instrumentation. The American Standardization of Testing Methods (ASTM) published the ASTM D5453 method specifically for the petroleum industry, covering the determination of the Total Sulfur content in liquid petroleum products by ultraviolet fluorescence detection.
Working range Total Sulfur: 1.0 – 8,000 mg/kg
Boiling range: 25 – 400 °C
Viscosities of samples: 0.2 – 20 cSt (mm2/s) at room temperature
Sample types: Naphthas, Distillates, Engine Oil, Ethanol, Fatty Acid Methyl Ester (FAME); Engine Fuel such as Gasoline, Oxygen Enriched Gasoline (Ethanol Blends, E-85, M-85, RFG), Diesel, Biodiesel, Diesel/Biodiesel Blends, Jet Fuel
To comply with ASTM D5453, TSHR offers NEXIS TS and TS 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. The use of boat inlet technique at the TSHR NEXIS and 6000 models is recommended when analyzing high boiling point and viscous samples.
ASTM Method D5453 is commonly used to determine Total Sulfur in liquid hydrocarbons. The boiling range of these hydrocarbons can vary from 25 to 400ºC. This method calls for the sample to be directly injected or placed in a sample boat and then inserted into a high temperature tube for combustion where the sample is oxidized into sulfur dioxide (SO2). The sample is exposed to ultraviolet light and detected by a photomultiplier. This application note will examine the Total Sulfur content of diesel fuel samples using the NEXIS Total Nitrogen/Total Sulfur combustion analyzer.
ASTM D5453 covers the determination of Total Sulfur in concentrations ranging from about 1 to 8000 mg/kg in a wide range of liquid hydrocarbons and automotive fuels having a boiling point range of 25˚C to 400˚C and viscosities between 0.2 and 20 Cst (mm²/s) at ambient temperature.
Sulfur 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 sulfur concentration of various type of automotive fuels and related products. This Application Note shows the analysis performance of a set of automotive fuel samples. The system design and methodology of the EST NEXIS Total Sulfur analyzer is thoroughly tested for response linearity and repeatability, to validate its performance according to ASTM D5453.

ASTM Method D5453-19a describes the combustion and Ultra Violet Fluorescence (UV-F) detection of Sulfur in light hydrocarbons, engine fuels and oils. However, even an optimized detector may identify nitrogen oxide as Sulfur dioxide, as they both emit at the same wavelength. This problem can result in false positives or biased total sulfur data. EST Analytical has developed an integrated tunable Nitrogen Oxide interference elimination module, called the TRINITYTM Module. This new module ensures there is no interference when analyzing high nitrogen containing samples thus delivering accurate total Sulfur data.
