UV fluorescence sulfur analyzer for petrochemical testing

UV fluorescencemeasureSulfur analyzerPrinciple of determination using ultraviolet fluorescence method，Suitable for determining the total sulfur content in crude oil, distillate oil, liquefied petroleum gas, plastics, petrochemical products, food, etc. After being introduced into the high-temperature cracking furnace, the sample undergoes cracking oxidation reaction. In1000℃At high temperatures, the sample is vaporized and undergoes oxidative cracking, with sulfides quantitatively converted to 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 this radiation and causes some electrons to shift to high-energy orbitals. Once electrons return to their original orbits, excess energy is released in the form of light and detected by a photomultiplier tube at a specific wavelength. The emitted fluorescence is specific to sulfur and proportional to the sulfur content in the original sample. After amplification by a microcurrent amplifier and computer data processing, it can be converted into an electrical signal proportional to the intensity of light. By measuring its size, the sulfur content of the corresponding sample can be calculated.

Main Features

● Computer control operation can achieve human-machine dialogue, and data and peak shapes can be automatically stored and printed.

● The instrument adopts a new type of quartz cracking tube, which can increase the injection volume and reduce measurement errors.

● The automatic on/off of the cooling fan eliminates the hassle of waiting for the sample to shut down, saving time and effort.

● The darkroom system adopts new foreign technologies, and key components use imported detection elements, which improves the detection accuracy of the instrument

● The instrument adopts an imported membrane dryer to absorb moisture, saving the trouble of frequently replacing magnesium perchlorate and reducing the problem of air leakage.

● The use of computer-controlled temperature has improved the temperature control accuracy of the instrument and is less prone to overheating.

● Using air cooling instead of water cooling saves water resources.

● Existing calibration curves can be retrieved and calibrated with standard samples for sample analysis.
