Determination of Impurities in Dry Chlorine
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.
Typical measuring ranges
0 – 90 %vol chlorine
0 – 1 %vol hydrogen
0 – 5 %vol oxygen
0 – 2 %vol CO2
0 – 2 %vol nitrogen
