SH0689 UV fluorescence sulfur meter
SH0689 Ultraviolet Fluorescence Sulfur Analyzer uses ultraviolet
fluorescence method to determine the principle.
In line with ASTM D5453, SH/T 0689-2000 and other standards,
suitable for the determination of total sulfur content in crude
oil, distillate oil, liquefied petroleum gas, plastics,
petrochemical products, food and other.
After the sample was introduced into the high temperature cracking
furnace, the sample underwent cracking oxidation reaction.
At a high temperature of about 1000℃, the samples were completely
gasified and oxidized, and the sulfur compounds in them were
quantitatively converted to sulfur dioxide.
Ultraviolet Fluorescence ASTM D5453 Sulfur Analyzer Biodiesel
Sulfur Content Tester
Reaction gas carried by carrier gas, through the membrane dryer to
remove the moisture, into the reaction chamber.
Sulfur dioxide is irradiated by ultraviolet light at certain
wavelengths and absorbs this radiation to divert some electrons
into high-energy orbits.
Once the electrons have returned to their original orbitals, the
excess energy is released as light, detected by a photomultiplier
tube at a specific wavelength, emitting fluorescence that is
completely specific to the sulfur and proportional to the amount of
sulfur in the original sample.
After being amplified by micro-current amplifier and processed by
computer, it can be converted into electrical signal proportional
to light intensity, and the sulfur content of the corresponding
sample can be calculated by measuring its size.
Scope of application: It is suitable for the determination of total
sulfur content in gasoline, diesel oil, lubricating oil, crude oil,
distillate oil, liquefied petroleum gas, gas, natural gas,
plastics, petrochemical products, food, coal and so on.
Compliance with standards: ASTM D5453, SH/T 0689-2000 and other
standards.
(It meets the testing standard requirements of national five
national six gasoline diesel)
