BD-D5453-0689A fully automatic UV fluorescent oil sulfur tester is designed and manufactured in accordance with the requirements of the People's Republic of China industry standard SH/T 0689 "Determination of total sulfur content of light hydrocarbons, engine fuels and other oil products (ultraviolet fluorescence method)", and is suitable for testing in accordance with SH/T 0689 Standard, using ultraviolet fluorescence method to measure total sulfur content, suitable for testing the sulfur content of gasoline and diesel including National V standards.
It can be widely used in petroleum, chemical industry, electric power, coal, food, environmental protection and other fields. It is currently the most advanced sulfur analysis instrument at home and abroad.
Applies to the requirements of ASTM D 5453 standard.
Main technical features
Windows operating platform, computer controls analysis, data processing and other processes, displaying the working status of the entire process; test parameters and results can be saved or printed; historical data query and graphic playback can be realized to facilitate comparison and analysis.
The instrument adopts the latest internationally popular pulsed ultraviolet fluorescence analysis method. By modulating and demodulating the light source signal, it effectively avoids the unstable sampling value caused by the attenuation of the ultraviolet light signal. It has a lower detection limit and higher detection accuracy, and can meet the requirements of National VI and higher standard oil sulfur content testing requirements.
A truly fully automatic liquid sampler with 156 sample positions, enabling unattended analysis of samples, accurate positioning, and stable and reliable performance.
Use a mass flow meter to accurately control the gas flow rate to avoid interference from gas flow rate and pressure fluctuations on the measurement, obtain the highest decomposition efficiency, and make the analysis results repeatable and stable.
Automatically replace standards or samples, automatically clean, automatically eliminate bubbles, automatically draw standard curves, etc.
The standard sample is back-standardized for single-point calibration, and the high pressure can be adjusted arbitrarily without redoing the standard curve.
Reaction chamber: The reaction chamber has good anti-light leakage effect. At the same time, it adopts double anti-leakage (light and gas) processing technology to make the reaction chamber light-proof and sealed without air leakage, thus significantly improving the detection sensitivity and repeatability, and the measurement data results have reached International advanced level (company's proprietary technology).
If the air source pressure is unstable, automatic shutdown protection is provided to avoid system contamination.
The instrument adopts internationally popular circuits and imported components, which reduces instrument noise and improves detection sensitivity.
Using imported high-quality heating furnace wire, the cracking furnace has a longer service life.
The imported xenon lamp is used as the ultraviolet light source to replace the traditional zinc lamp. The cost does not increase and the service life is extended to more than 5 years. The good stability ensures the accuracy of the detection and greatly reduces the maintenance cost.
Core components: The core components of the instrument, such as membrane dryers, filters, xenon lamps, photomultiplier tubes, syringes, and filter membranes, are original accessories imported from the United States, Japan, and Europe, ensuring the quality and safety of the instrument. Accuracy of analysis results.
Standard imported SGE syringe.
Equipped with imported filter membrane, which can effectively prevent the pollution of the membrane dryer and detection room.
Instrument calibration: Standard samples imported from the United States and Japan are used to calibrate the instrument to ensure the accuracy of instrument measurement.
The open lims database management mode facilitates database retrieval and management.
Optional dual-burner furnaces can be used to realize multiple functions in one machine and meet the needs of gas, liquid and solid detection.
18. A nitrogen digester is optional to eliminate high nitrogen interference and meet the detection of high nitrogen and low sulfur products.
