The instrument is efficient, high-precision, simple to operate, stable and reliable, representing the international advanced level. It is used in the determination of the total sulfur content of liquid products in petrochemical production, scientific research and sales enterprises, customs, commodity inspection, technical supervision systems and other fields.

● Windows operating platform, computer control analysis, data processing and other processes, and display the working status of the whole process; Test parameters and results can be saved or printed; It can realize historical data query and graphic playback for comparison and analysis.
● The instrument adopts the latest internationally popular pulse ultraviolet fluorescence analysis method. By modulating and demodulating the light source signal, it can effectively avoid the sampling value instability caused by the attenuation of the UV lamp signal. The lower detection limit and higher detection accuracy can meet the sulfur content detection requirements of national VI and higher standards.
●The real automatic liquid injector with 156 sample positions realizes unattended analysis of samples, accurate positioning and stable and reliable performance.
● The mass flowmeter is used to accurately control the gas flow rate, avoid the interference of gas flow rate and pressure fluctuation on the measurement, obtain the highest decomposition efficiency, and make the analysis results repeated and stable.
● Automatic replacement of standard sample or sample, automatic cleaning, automatic elimination of bubbles, automatic drawing of standard curve, etc.
● Single point correction for reverse standard of standard sample. The high voltage can be adjusted arbitrarily without redoing the standard curve.
● Reaction chamber: the reaction chamber has a good light leakage prevention effect. At the same time, the double leakage prevention (light and gas) processing process is adopted to make the reaction chamber sealed against light without air leakage, so that the detection sensitivity and repeatability are significantly improved. The measurement data results have reached the international advanced level (proprietary technology of the company).
● If the air source pressure is unstable, it will be automatically shut down for protection to avoid system pollution.
● The instrument adopts internationally popular circuits and imported components to reduce instrument noise and improve detection sensitivity.
● Imported high-quality heating furnace wire is adopted, and the service life of cracking furnace is longer.
● The imported xenon lamp is used as the UV light source to replace the traditional zinc lamp. The cost is not increased, and the service life is extended to more than 5 years. The good stability ensures the accuracy of detection, and greatly reduces the maintenance cost.
● Core components: the core components of the instrument, such as membrane dryer, filter, xenon lamp, photomultiplier tube, sampling probe, filter membrane and other main accessories, are original accessories imported from the United States, Japan and Europe, ensuring the quality of the instrument and the accuracy of the analysis results.
● 10, 25 and 50μL imported sample injection needles are optional, and the injection volume can be set according to requirements.
● Equipped with imported filter membrane, it can effectively prevent the pollution of membrane dryer and detection room.
● Instrument calibration: the standard samples imported from the United States and Japan are used for instrument calibration to ensure the accuracy of instrument measurement.
● Open LIMS database management mode to facilitate database retrieval and management.
● Dual combustion furnaces can be configured to realize one machine with multiple functions and meet the requirements of gas-liquid solid detection.
● Nitrogen digester can be selected to eliminate high nitrogen interference and meet the detection of high nitrogen and low sulfur product.
