Description
ASTM D 5453 Automatic UV Fluorescent Oil Sulfur Tester Petroleum Products Sulfur Content Analyzer
Introduction
This instrument is designed and manufactured according to the requirements of SH/T 0689 "Determination of Total Sulfur Content of Light Hydrocarbons and Engine Fuels and other Oils (Ultraviolet fluorescence Method)", which is applicable to the determination of total sulfur content by ultraviolet fluorescence method according to SH/T 0689 standard. It is suitable for the test of sulfur content of gasoline and diesel including national V standard. It can be widely used in petroleum, chemical industry, electric power, coal, food, environmental protection and other fields, and is an advanced sulfur analysis instrument at home and abroad.
This instrument is also suitable for the requirements of ASTM D 5453.

Main technical features
1, Windows operating platform, computer control analysis, data processing and other processes, display the whole process of work; Test parameters and results can be saved or printed; It can realize historical data query and graphical playback, which is easy to compare and analyze.
2, the instrument adopts the latest international popular pulsed ultraviolet fluorescence analysis method, through the modulation and demodulation of light source signal, effectively avoid the instability of the sample value caused by the ultraviolet lamp signal attenuation, the detection limit is lower, the detection accuracy is higher, and can meet the national VI and higher standard oil sulfur content detection requirements.
3, the real automatic liquid sampler, 156 sample locations, to achieve unattended analysis of samples, accurate positioning, stable and reliable performance.
4, the mass flow meter is used to accurately control the gas flow rate, avoid the interference of the gas flow rate and pressure fluctuations on the measurement, and obtain the highest decomposition efficiency, so that the analysis results are repeated and stable.
5, automatic replacement of standard samples or samples, automatic cleaning, automatic elimination of bubbles, automatic drawing of standard curves.
6, the standard sample reverse standard single point correction, the high pressure can be adjusted arbitrarily, no need to redo the standard curve.
7, the reaction chamber: the reaction chamber anti-leakage effect is good, while the use of double anti-leakage (light, gas) processing technology, so that the reaction chamber light sealed without leakage, so that the detection sensitivity and repeatability significantly improved, the measurement data results reached the international advanced level (the company's proprietary technology).
8, the air source pressure is unstable, automatic shutdown protection, to avoid system pollution.
9, the instrument adopts international popular circuits and imported components, which reduces the noise of the instrument and improves the detection sensitivity.
10, the use of imported high quality heating furnace wire, cracking furnace longer service life.
11, the use of imported xenon lamp as a UV light source, instead of the traditional zinc lamp, the cost does not increase, the service life is extended to more than 5 years, good stability to ensure the accuracy of the detection, while greatly reducing maintenance costs.
12, core parts: the core parts of the instrument membrane dryer, filter, xenon lamp, photomultiplier tube, injection needle, filter film and other main accessories are imported from the United States, Japan, Europe, to ensure the quality of the instrument and the accuracy of the analysis results.
13, standard imported sge injection needle.
14, with imported filter membrane, can effectively prevent the pollution of membrane dryer and test room.
15, instrument calibration: The United States and Japan imported standard samples for instrument calibration, to ensure the accuracy of instrument measurement.
16, open lims database management mode, easy to database search management.
17, optional configuration of dual combustion furnace, to achieve a machine multi-energy, to meet the needs of gas-liquid solid detection.
18, optional nitrogen digester, eliminate high nitrogen interference, meet the detection of high nitrogen and low sulfur products.
