Precise and Accurate Detection of Total Sulfur in Biodiesel Fuels – ASTM D5453

Traditionally, combustion and Ultra Violet Fluorescence (UV-F) have been used for accurate analysis of sulfur in motor fuels as per ASTM Method D5453. However, even an optimized detector may identify nitrogen as nitrogen oxide, which emits at the same wavelength as sulfur dioxide, resulting in inaccurate analysis. This application note describes the Total Sulfur analysis of Fatty Acid Methyl Ester (FAME) samples on the EST Analytical TS 7000 instrument as per ASTM Method D5453.

Our Impact

TSHR has been helping labs achieve their elemental analysis goals with dedicated solutions. Our vision is to develop innovative reliable combustion analyzers that enable customers to make their work productive and more easier.

To help labs excel we offer Application Notes across the Combustion Analyzer product line. They are a resource that explains the technology, performance, and abilities of our products as used against certain methodologies and or applications.

Whether your needs center around an ASTM Standard or EN/ISO methods, or a sample matrix-based outcome TSHR has you covered. If you don’t see the technical direction you need, simply contact us. We also offer sample analysis in our onsite Applications Lab.
