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

EST Analytical has been helping labs achieve their analytical goals for over 30 years. Our vision is to engineer reliable laboratory instruments that enable partners to make the world a better place.

To help labs excel we offer Application Notes across our entire 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 a USEPA method, an ASTM Standard, or a sample matrix-based outcome EST 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.
