CloraClora 2XP Ultra-trace
MWDXRF Chlorine Analyzer

Clora? 2XP is designed for use with liquid hydrocarbons such as aromatics, distillates, heavy fuels and crude oils, as well as aqueous solutions. The enhanced precision of Clora 2XP is ideal for testing related to catalyst poisoning in reformers or for sites with fluid catalytic crackers and hydrocrackers monitoring very low levels of chlorine.


Clora 2XP Ultra-trace 

MWDXRF Chlorine Analyzer

  • Using MWD XRF monochromatic wavelength dispersive X-ray fluorescence technology, ultra-low background
  • LOD: 0.07 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
  • Automatic sulfur correction

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 ?) 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.
