UV Fluorescence Sulfur Meter RT ～ 1200 ℃ Measure 0.1 ～ 10000mg/L Ppm ASTM D5435

SH0689 UV fluorescence sulfur meter

The UV fluorescence sulfur analyzer adopts the principle of UV fluorescence measurement and is suitable for measuring 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 a cracking oxidation reaction. At a high temperature of around 1000 ℃, the sample is completely gasified and undergoes oxidative cracking, with sulfides quantitatively converted into sulfur dioxide. The reaction gas is carried by the carrier gas, and the water is removed by the membrane dryer before entering the reaction chamber. Sulfur dioxide is exposed to specific wavelengths of ultraviolet radiation, absorbing this radiation and causing some electrons to turn towards high-energy orbitals. Once electrons return to their original orbitals, excess energy is released in the form of light and detected by photomultiplier tubes at specific wavelengths. 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 directly proportional to the light intensity. By measuring its size, the sulfur content of the corresponding sample can be calculated.

The 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 Computer fan is automatically turned on and off, which saves time and labor by eliminating the trouble of waiting for the sample to be turned off.

● The darkroom system adopts new foreign technology, and key components use imported detection components to improve the detection accuracy of the instrument.

● The instrument adopts imported membrane dryer to absorb water, which saves the trouble of replacing Magnesium perchlorate frequently and reduces the problem of air leakage.

● The use of computer control for temperature has improved the temperature control accuracy of the instrument and is not prone to overheating.

● Replacing water cooling with air cooling saves water resources.

● You can retrieve existing calibration curves and calibrate them with standard samples for sample analysis.
