描述:
This instrument is a new generation of precision instruments developed in combination with the principle of UV fluorescence measurement and computer technology. It is the most advanced total sulfur analyzer in China. It conforms to ASTM D5453, SH / T 0689 and other standards. The instrument complies with national refined oil Arbitration standard for determination of total sulfur content. It widely used in the determination of crude oil, hydrocarbons and engine fuel, LPG, plastics, petrochemical products, food and so on.
The instrument uses the principle of ultraviolet fluorescence measurement, when the sample is introduced into the pyrolysis furnace, the sample undergoes the cracking oxidation reaction, in which the sulfide is quantitatively converted into sulfur dioxide, carried by the carrier gas, the moisture is removed by the membrane dryer, (SO2 *), when the SO2 * return to the steady state of sulfur dioxide emission fluorescence, the release of energy received by the photomultiplier tube, and then amplified by the micro-current amplifier, and then to the SO2 * 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 of the sample.

Features
1, computer control, it can achieve man-machine dialogue, data and peak shape can be automatically stored and printed.
2, the operating software and LIMIS system can be connected to achieve automatic data transmission.
3, the instrument uses a new quartz cracking tube, which can increase the injection volume, reduce measurement error, improve the sensitivity of the instrument, higher repeatability.
4, cooling fan can automatically turn on and off, so you can save the trouble of waiting for shutdown, saving time and effort.
5, the darkroom system uses the latest technology, the key components of imported detection components to improve the instrument's detection accuracy and sensitivity.
6, the instrument uses imported film dryer to absorb water, eliminating the need to replace the frequent trouble of magnesium perchlorate, while reducing the leakage problem.
7, the instrument uses computer-controlled temperature, improve the accuracy of the instrument temperature control, and difficult to over-temperature.
8, the instrument uses air-cooled instead of water-cooled, saving water resources.
9, the user can retrieve the existing calibration curve, after use the standard sample to calibration it, you can analysis sample.
