ASTM D7183 Standard Test Method for Determination of Total Sulfur in Aromatic Hydrocarbons and Related Chemicals by Ultraviolet Fluorescence

The ASTM D7183 standard outlines the test method for determining total sulfur in aromatic hydrocarbons and related chemicals using UV fluorescence. This method is applicable to samples with sulfur concentrations up to 10 mg/kg. The limit of detection (LOD) is 0.03 mg/kg sulfur, and the limit of quantitation (LOQ) is 0.1 mg/kg sulfur. The method is designed to measure sulfur in various light volatile aromatic hydrocarbons, their derivatives, and related chemicals.

The method provides comprehensive information about the sulfur content in hydrocarbons. Sulfur compounds can significantly impact the quality, performance and usability of these hydrocarbons, especially in industrial applications where purity is critical. The total sulfur, a sum parameter including all sulfur compounds present in the sample, is providing a complete picture of sulfur contamination. This is essential for catalyst protection and prevention of corrosion and fouling for various industrial processes.

ASTM D7183 is a crucial standard for determining total sulfur in aromatic hydrocarbons and related chemicals using ultraviolet fluorescence. The method's reliability makes it an indispensable tool for ensuring the quality and safety of aromatic hydrocarbons in various industrial applications.

With its multi EA 5100 and compEAct elemental analyzers, Analytik Jena offers two analyzers that are specially suited for the challenging task of sulfur analysis in the trace range. The combination of efficient, catalyst-free combustion, high-performance drying of the measured combustion gas, and powerful HiPerSens detection allows reliable analysis of sulfur traces down to 30 µg/kg.
