ASTM D5453 Ultraviolet Fluorescence UV Sulfur Analyzer RT ～ 1200℃ Measure 0.1～10000mg/L

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. 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.

Main Features

● Computer-controlled operation enables human-machine interaction, with automatic storage and printing of data and waveform patterns.

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

● The instrument employs a novel quartz cracking tube, which increases the sample injection volume and reduces measurement errors.

● The cooling fan operates automatically, eliminating the need to wait for it to turn off after completing sample processing— saving both time and effort.

● The darkroom system employs advanced foreign technologies, with key components utilizing imported detection elements to enhance the instrument's measurement accuracy.

● The instrument utilizes imported membrane dryers for moisture absorption, eliminating the need for frequent replacement of magnesium perchlorate and reducing gas leakage issues.

● Computer-controlled temperature regulation enhances the instrument's thermal control accuracy and prevents overheating.

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

● Existing calibration curves can be retrieved and used for sample analysis after standardization with reference standards.
