Accurate Determination of Total Sulfur with Nitrogen Interference - ASTM D5453-19a
ASTM Method D5453-19a describes how to determine total sulfur in the combustion and Ultra Violet Fluorescence (UV-F) detection of 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 to determine total sulfur. This new module ensures there is no interference when analyzing high nitrogen containing samples thus delivering accurate total Sulfur data.
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.
