Clora 2XP
Supplier: XOS, Inc

Clora 2XP


Clora 2XP complies with ASTM D7536 and D4929-C standard test methods, and is ideal for testing related to catalyst poisoning in reformers, or for sites with fluid catalytic crackers and hydrocrackers. It delivers twice the precision and offers exceptional analysis for the determination of chlorine in liquid hydrocarbon samples such as aromatics, distillates and heavy fuels, and aqueous solutions. Clora 2XP is powered by the same MWDXRF technology as our signature instrument - Sindie. This direct measurement technique does not require gasses or high temperature processes equating to easy operation and minimum maintenance requirements.
This model delivers a limit of detection of 0.07 ppm and dynamic range up to 3000 ppm (measures catalysts).

  • Easy to use
  • Extremely low maintenance
  • Total chlorine analysis
  • For use in multiple application areas
  • Hassle-free sample prep
