UV Fluorescence Sulfur Analyzer 0.1-10000mg/L ASTM D5453

Product Specification

SH0689 UV Fluorescence Sulfur Analyzer

The UV fluorescence sulfur analyzer adopts the principle of UV fluorescence method and is 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. At a high temperature of around 1000 ℃, the sample is completely 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 completely 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.

SH0689 UV fluorescence sulfur analyzer complies with ASTM D5453, SH/T 0689-2000 and other standards

Main features

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

The operating software can be connected to the LIMIS system to achieve automatic data transmission.

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 to improve 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.

It is possible to retrieve existing calibration curves and calibrate them with standard samples for sample analysis.
