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