Introduction: This instrument is a special X-ray fluorescence analyzer designed and manufactured according to the requirements of the People's Republic of China GB / T 17040-2008 "Determination of sulfur content of petroleum products (energy dispersive X-ray fluorescence spectrometry)". The instrument uses the principle of energy dispersion, mechanical and electrical integration of computer design, analysis of fast and accurate. Its reproducibility, reproducibility are in line with national standards GB / T 17040-2008 "sulfur content of petroleum products (energy dispersive X-ray fluorescence spectrometry)" and GB / T 11140-1989 "sulfur content of petroleum products (X-ray Spectrum) "the relevant requirements, but also fully comply with the US national standard ASTMD4294-02 requirements. Features: 1, using fluorescence intensity ratio analysis method, detection of wide variety, wide range, fast analysis, less sample consumption. 2, the use of mechanical and electrical integration of computer design, LCD display, user interface, man-machine dialogue, with automatic diagnostic function to determine the working status of the instrument and electrical parameters, temperature, air pressure correction, hydrocarbon ratio (C / H) can be amended. 3, the use of disposable Mylar membrane sample cup, to avoid cross-contamination. 4, the instrument has a standard serial communication RS-232C interface, can be achieved with the computer communication. 5, safe X-ray protection measures, the Shanghai Institute of Preventive Medicine rigorous testing, individuals and groups no X-ray radiation damage. The biggest feature of the instrument is: the minimum test index 7ppm, with 12 calibration (calibration), reliable X-ray radiation protection measures. The main purpose: 1, measuring crude oil, oil, heavy oil, diesel, kerosene, gasoline, naphtha total sulfur content percentage content; 2, the measurement of coal chemical products (such as primary benzene), other liquid samples of the total sulfur or sulfur compounds content; 3, the determination of the total sulfur or SO3 content in the fine powder sample; Technical indicators: 1, sulfur range: 7ppm ~ 5%. 2, precision: a: repeatability (r): <0.02894 (X + 0.1691); b: Reproducibility (R): <0.1215 (X + 0.05555). 3, the amount of sample: (2 ~ 3) ml (equivalent to the depth of the sample 3mm ~ 4mm). 4, measurement time: 60 seconds, 120 seconds, 240 seconds, 300 seconds, 600 seconds, any set. 5, the sample measurement: a single sample of automatic measurement, the number of measurements 2,3,5,10,50 times any set, the end of the measurement gives the average and standard deviation. 6, the correction curve: the instrument can store nine calibration curve, five for a dollar a straight line, four for the binomial parabola. 7, calibration (calibration) sample: 12 (10ml / 个). 8, working conditions: temperature: (10 ~ 35) ℃; relative humidity: ≤ 85% (30 ℃). 9, the working power: AC220V ± 20V, 50Hz; rated power 30W. 10, Dimensions: 468mm × 368mm × 136mm (length × width × height). 11, weight: 13kg (net weight).
