Application area:
Total sulfur content in crude oil, petroleum, heavy oil, diesel, kerosene, gasoline, naphtha, and other oil products;
Total sulfur content in coal chemical products, such as primary benzene;
Total sulfur or sulfide content in solid fine powder samples, such as carbon materials including anode carbon blocks, petroleum coke, modified asphalt, etc.
The measurement of total sulfur or sulfur content in lubricating oil and petroleum additives;
Total sulfur or sulfide content in other liquids.
Technical feature:
The system features a microcomputerized electromechanical design with an 8-inch wide-view capacitive touchscreen (1027*768) display. The backlight brightness can be adjusted via software, and the interface is intuitive and aesthetically pleasing without requiring a keyboard.
The detection range is wide, the speed of analysis is fast, and the consumption of standard sample is less.
The method of analyzing the ratio of fluorescence intensity was adopted, and the temperature and pressure were automatically corrected, and the C/H ratio was also corrected.
The automatic diagnosis function of the instrument, which can judge the working state and electrical parameters of the instrument;
The use of disposable Mylar membrane sample cups can avoid cross-contamination, and the sample cups are made by multi-functional pressing parts, which is quick and convenient.
The sample position is accurate, the sample is easy to place and the oil leakage parts are easy to change, and the possibility of contamination of the detection system is avoided.
The instrument has a large storage capacity, which can store 4096 content analysis results, 8192 counting measurement data and 16 instrument calibration results by default. The data can be queried and uploaded to computer through RS-232 standard serial communication port.
The system has the function of automatic peak stabilization, and can adjust the high voltage automatically to correct the error when the performance of the detector is declining.
The system automatically selects the working curve upon startup without user intervention.
Users can select the measurement unit: ppm or (m/m)%
The safe radiation protection measures will not cause ionizing radiation harm to individuals and groups.
