The SH407 X-ray Fluorescence Sulfur Analyzer utilizes the energy-dispersive principle with an electromechanical integrated microcomputer structure, enabling fast and accurate analysis. It complies with ASTM D4294, the standard test method for sulfur content in petroleum products by energy-dispersive X-ray fluorescence spectrometry.
Its repeatability and reproducibility conform to the relevant specifications of national standards GB/T 17040-2008 Determination of Sulfur Content in Petroleum Products (Energy-Dispersive X-ray Fluorescence Spectrometry) and GB/T 11140-1989 Determination of Sulfur Content in Petroleum Products (X-ray Spectrometry), and fully meet the requirements of ASTM D4294-02.
For many years, X-ray fluorescence sulfur analyzers have been the preferred choice in the petroleum industry. Ongoing enhancements in performance and operability allow us to provide an improved instrument that meets your practical demands. Our XRF sulfur analyzers comply with ASTM D4294, and represent a highly cost-effective solution for the determination of sulfur in petroleum products.
The SH407 Fluorescence Sulfur Analyzer is mainly used to measure the total sulfur mass percentage in crude oil, petroleum, heavy oil, diesel fuel, kerosene, gasoline and naphtha. It can also determine total sulfur or sulfur compounds in coal chemical products (such as crude benzene) and other liquid samples.
In addition, it can be applied to determine total sulfur or SO₃ content in fine powder samples.
I. Main technical features
1. Adopting the fluorescence intensity ratio analysis method, the detection variety is wide, the detection range is wide, the analysis speed is fast, and the consumption of the standard sample is small.
2.the use of mechanical and electrical integrated microcomputer design, liquid crystal display, man-machine interface dialogue, with automatic diagnosis function, to judge the working state of the instrument and electrical parameters, temperature, air pressure automatic correction, carbon hydrogen ratio (C/H) can also be corrected.
3. Use disposable Mylar sample cup to avoid cross contamination.
4. safe X-ray protection measures, after strict testing, no X-ray power radiation damage to individuals and groups.
