ASTM 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

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 TS 6000 and TS 7000 series models and combined instrument configurations like TN/TS 6000 and TN/TS 7000 models with semi-automatic syringe or fully automatic liquids injection through HR 7000 models Liquids Autosampler configurations. The use of boat inlet technique at the TSHR 6000 models is recommended when analyzing high boiling point and viscous samples.
