NEXIS VP TRINITY TNTS ASTM D5453-19a method
Simultaneous analysis of Total Sulfur and Total Nitrogen in liquid hydrocarbon samples are widely used in R&D, production and routine quality control labs in compliance with several ASTM methods. Combustion and Ultraviolet Fluorescence (UV-F) have been used for accurate analysis of sulfur in motor fuels as per ASTM D5453-19a. However, even an optimized UV-F detector may identify nitrogen oxide as sulfur dioxide, which emits at the same wavelength as sulfur dioxide, into positive interferences and biased sulfur data.
EST Analytical – TSHR has developed an integrated solution, the TRINITY™ in NEXIS and NEXIS VP models TN/TS analyzers, in order to have maximum flexibility when it comes to accurate and interference free total sulfur analysis as well as simultaneous analysis of total sulfur and nitrogen with minimum user handling
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.
