HSCA-2000 Total Sulfur Analyzer

This analyzer is used to determine trace sulfur content in petroleum products and liquid organic chemicals, including gasoline, naphtha, kerosene and diesel, methanol, benzene, ester, ketone, ether, etc. The analyzer can be applied to process control and product quality control during the processing and blending of petroleum products. The measurement indicators meet the requirements for total sulfur inspection in National IV and National V of automotive fuels.

 

Measuring principle: energy dispersion method X-ray fluorescence method (EDXRF)

 

X-ray fluorescence is a phenomenon caused by high-energy X-ray excitation of the inner orbital electrons of atoms. When X-rays excite the inner electrons of an atom, causing the electrons to escape from the inner layer and generate holes in the inner electron orbits, the atom will then become unstable in an energetic state. The electrons in the outer orbit will migrate to the holes in the inner layer, and energy will be released during the migration process, that is, X-ray fluorescence phenomenon will occur. The energy of the generated X-fluorescence is related to the atomic structure. For specific element atoms, X-ray excitation with specific energy will produce characteristic X-fluorescence. For sulfur atoms, the K layer electrons are excited to escape, and the L layer electrons migrate to the K layer. The energy of this particular X-ray fluorescence is mainly the S-Kα line, whose energy is 2.31 keV, and a small amount is S- The Kβ line has an energy of 2.46 keV.

 

The X-ray fluorescence energies of element atoms close to sulfur atoms are listed in the table below:

 

Elemental energy keV (kiloelectron volts)

 

Sulfur, S-Kα 2.31

 

Argon, Ar-Kα 2.96

 

Titanium, Ti-Kα 4.51

 

Iron, Fe-Kα 6.40

 

Since the intensity of characteristic X-ray fluorescence is proportional to the number of sulfur atoms in the sample, the sulfur content in the sample can be directly detected by measuring the X-ray fluorescence of the sample.
