Features

Signal 

MWDXRF Silicon Analyzer

  • Using MWD XRF monochromatic wavelength dispersive X-ray fluorescence technology, ultra-low background
  • LOD: 0.65 ppm @ 600 s
  • Simple sample preparation and instrument operation process, fast detection
  • Fits on any lab bench, Just plug-in and measure
  • Extremely low maintenance: no conversion gasses, heating elements, columns, or quartz tubing
  • No moving parts in the analyzer



Working principle

A monochromatic X-ray beam with a wavelength suitable to excite the K-shell electrons of sulfur is focused onto a test specimen contained in a sample cell. The fluorescent Kα radiation at 0.5373 nm (5.373 Å) emitted by sulfur is collected by a fixed monochromator (analyzer). The intensity (counts per second) of the sulfur X rays is measured using a suitable detector and converted to the concentration of sulfur (mg/kg) in a test specimen using a calibration equation.



Specifications

  • LOD: 0.65
  • Dynamic Range: 0.65 ppm–3000ppm
  • Sample Volume: <10ml
  • Using Prolene film
  • Power only, no combustion and gas consumption
  • With the function of multi calibration curve storage, can measure different samples
  • Measurement: User selectable: 30-900 s

Applications

Petrochemical products such as gasoline, diesel, blending distillate, jet fuel, kerosene, biodiesel, Biodiesel Blended fuel, ethanol gasoline, heavy oil, etc. It is suitable for petrochemical enterprises, refining, quality inspection departments, third-party testing and other industries.
