SH/T 0689-2000, ASTM D5453-2006 , EN ISO 20846:2004, GB 17930-2011, GB 19147-2009, ISO 20846-2011, BS EN 15486-2007
ASTM D5453 is an orthodox test method to ascertain the total sulfur in liquid hydrocarbons containing 1.0 to 8000 mg/kg total Sulfur, which boil in the range from approximately 25 °C to 400 °C and with viscosities at room temperature of between approximately 0.2 and 20 cSt (mm2/S). This method of testing also has applications in determining the total sulfur in liquid hydrocarbons which contain fewer than 0.35% (m/m) halogen(s).
Working Principle:
After being introduced into the high-temperature cracking furnace, the sample undergoes cracking oxidation reaction. At high temperature, the sample is gasified and oxidized, and the sulfides are quantitatively converted into sulfur dioxide
The reaction gas is carried by the carrier gas, and after passing through a membrane dryer to remove its moisture, it enters the reaction chamber
Sulfur dioxide is exposed to specific wavelengths of ultraviolet radiation, which absorbs the radiation and causes the electrons to shift to high-energy orbitals. When the electrons return to their original orbitals, excess energy is released in the form of light, emitting fluorescence
The fluorescence signal is detected and received by a photomultiplier tube at a specific wavelength, and the emitted fluorescence is proportional to the sulfur content in the original sample. After amplification by a microcurrent amplifier and data processing by a computer, it is converted into an electrical signal proportional to the light intensity, and then the sulfur content of the sample is calculated
High Sensitivity:
The astm d5453 instrument is used to determine the total sulfur content by ultraviolet fluorescence method. It improves the ability of anti-jamming, and avoids the complicated operation of titration pool and factors of instability which used Coulometry. So the sensitivity of the instrument is greatly improved. The key components of the system adopt imported components to protect the detector light leakage and steam leakage and makes the machine has a reliable guarantee.
