Scope of application:
Ultraviolet fluorescence sulfur meter is a new-generation precision instrument developed based on the principle of ultraviolet fluorescence method and the combination of computer technology. It is an advanced total sulfur content meter in China, meeting ASTM D5453, SH/T 0689 and other standards. It is widely used to determine the total sulfur content in crude oil, hydrocarbon and engine fuel, LPG, plastics, petrochemical products and food.
Instrument using ultraviolet fluorescence determination principle, when the sample is introduced into the high temperature cracking furnace, after samples pyrolysis oxidation reaction, the sulfide into sulfur dioxide, quantitatively carried by the carrier, through the membrane dryer to take off the water, into the reaction chamber, and sulfur dioxide absorbing uv light energy into excited states of sulfur dioxide (SO2 *), when SO2 * returns to the stable state of sulfur dioxide emission fluorescence, the energy released by the photomultiplier receiving, then through micro current amplifier amplification, computer data processing, the reaction of luminous intensity is proportional to the generation of sulfur dioxide, The amount of sulfur dioxide is proportional to the total sulfur content in the sample, so the total sulfur content in the sample can be determined by measuring the luminous intensity.
Functional features:
1, computer control operation, can achieve man-machine dialogue, data, peak shape can be automatically stored and printed.
2. The operating software can be connected with LIMIS system to achieve automatic data transmission.
3. The instrument adopts new quartz cracking tube, which can increase the sample amount, reduce the measurement error, improve the sensitivity of the instrument and improve the repeatability.
4. Automatic switch of cooling fan saves the trouble of waiting for shutdown after completing the sample and saves time and effort.
5. The darkroom system adopts foreign new technology, and the key components are imported detection components, which improves the detection accuracy and sensitivity of the instrument.
6. The imported film dryer is adopted to absorb water, saving the trouble of replacing magnesium perchlorate frequently and reducing the problem of air leakage.
7, the use of computer control temperature, improve the temperature control precision of the instrument, and not easy to overtemperature.
8, the use of air cooling instead of water cooling, saving water resources.
9. The existing calibration curves can be obtained and calibrated with standard samples for sample analysis.
