Scope of application Sulfur content of petroleum products tester (X-ray spectroscopy) People's Republic of China in accordance with requirements of the standard GB/T11140, GB/T17040, ASTM D4294 specified in the design and manufacture of this instrument for the determination of trace sulfur content in petroleum products. Because it uses physical analysis methods, analytical speed, without complicated sample preparation, high precision, human error, low labor intensity, no pollution, it has been widely applied and basic replace other measuring sulfur in the international arena methods of analysis. Function characteristics 1, English operating system, man-machine interface of friendly exchanges. 2, detection time is short, the automatic test results within 30 seconds; automatic C / H ratio correction for multiple samples; 3, large-screen LCD display, automatic print measurement data; 4, using the X-ray tube excitation, the instrument can be used for a long while without source attenuation effects; 5, use of physical methods of analysis, the analysis does not contact does not destroy the sample, without chemical reagents; 6, instrument with integrated design, easy maintenance;
