Ultraviolet Fluorescence (UVF) Method Sulfur Content in Oil Analyzer ASTM D5453
Introduction:
The instrument is designed and manufactured according to the standards SH/T 0689-2000 Standard test method for determination of total sulfur in light hydrocarbons,motor fuels and oils by ultraviolet fluorescence,SH/T 0657-2007 Standard test method for trace nitrogen in liquid petroleum hydrocarbons by syringe/inlet oxidative combustion and chemiluminescence detection and ASTM D 5453 -2006 standard. It is widely used in petroleum,chemical industry,electric power,coal,food,environment proection and others.At present, GD-0689N is the advanced instrument to analyze the sulfur,nitrogen in China.
ASTM D5453:
It 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).
Method Summary:
A measured quantity of the hydrocarbon sample is either directly injected into the pyrotube of the analyzer at a controlled speed into the vaporization and combustion zones of the instrument. In the inlet zone the sample is transported by an inert stream of a carrier gas, typically Argon or Helium. The hydrocarbon is oxidized in a rich pure oxygen stream in the combustion zone at approximately 1000°C where it is converted into CO2, SO2 and H2O. After the gases exit the combustion zone they are passed through a semipermeable Nafion® membrane where the water is quantitatively removed. The gases enter the Sulfur reaction chamber where they are exposed to an UV light. The SO2 molecules absorb the radiation and become excited. The relaxation takes a few nanoseconds releasing a secondary energy which is captured by a Photo Multiplier Tube, amplified processed and recorded. The signal obtained is proportional to the total sulfur content of the original sample.
Main technical features
1. The instrument can detect the both sulfur and nitrogen,also could test the solid sample or liquid sample.
2. With the desktop computer,Windows system,man-machine direct conversation platform,It can set all prameters and make the test by the keyboard operation.
3. It adopts the control technology of the computer to automatically collect,process,store and print all data.with the wide linearity range of measurement,strong capacity of resisting disturbance,easy operation and reliable test results.
4. With the imported fluorescence excitation source,membrane desiccator,optical filter,metal encapsulated photomultiplier, It has the features of the high sensitivity,fast,stability,high precision,good consistency.
5. With the advanced temperature control system,fast and steadily warming rate,long service life,the temperature control accuracy ±3ºC during the temperature range,It can meet the test requirements.
