Introduction
Sulfur in combustion fuels is one of the major causes of acid rain. For this reasons many countries around the world have defined regulation to control the Sulfur content in fuels for combustion engines and power plants.
The KY-9000S Ultraviolet Fluorescence spectrometer is designed to measure total sulfur content for engine oils, fuels and hydrocarbons like gases, liquids, liquefied gases and even solids . The combustion UV fluorescence is preferred method for the quantitative determination of trace sulfur in a wide variety of hydrocarbon samples due to a series of instrumental advantages linear dynamic ranges of better than 10:3; excellent stability of the system that provides for high precision analysis; conversion of all sulfur species into a common analyte (SO2) eliminating matriz effects; quantitative and fast water stripping step to reduce the most important quenching source; unsurpassed signal to noise ratios, major contributor to the very low limits of detection achievable by this technique.
The ASTM D 5453 describes the method to determine the Total Sulfur content in a range of 1 to 8,000 ppm in process feeds, half-products and finished products .
The KY-9000S analyzer possesses all instrumental properties to guarantee fast, reliable and accurate results according to the ASTM D5453 method . Based on these characteristics the system meets with great ease the precision and accuracy qualifying it to report S contents.
