Features

Sindie 7039 

MWDXRF Sulfur Analyzer

  • Using MWD XRF monochromatic wavelength dispersive X-ray fluorescence technology, ultra-low background
  • LOD: 0.15ppm
  • 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
  • Accucell sample cup can be used
  • Option: autosampler



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.
