Online monitoring solutions for determination of impurities in dry chlorine - Monitoring and Testing

The purpose of determining impurities in dry chlorine (after compression) is a quality control measure to avoid contamination and off-spec product batches. Alternatively, chlorine purity can also be determined by measuring absolute levels of chlorine in dry chlorine, by means of multi-wavelength UV analysis.


The on-line analyzer system uses gas chromatography for monitoring chlorine, hydrogen, oxygen, CO2 and nitrogen.

Parameters: Chlorine purity

Typical measuring ranges

  • 0 - 90 %vol chlorine
  • 0 - 1 %vol hydrogen
  • 0 - 5 %vol oxygen
  • 0 - 2 %vol CO2
  • 0 - 2 %vol nitrogen
