The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride.
It is the technology used to produce chlorine and sodium hydroxide(lye/caustic soda), which are commodity chemicals required by industry.
The ETG 6900 P Cl2 perform the Chlorine in H2 gas analysis based on the NDUV techniques which’s well-know method to determine the concentration in a complex gas mixtures. This
gas analyzer uses modern optical components to achieve optimized analyzer results. We use a special LED-techology in order to get stable radiation emission. The result is a high
resolution gas analysis system which can detect gas concentration changes of less than 1 ppm.
Non-dispersive UV absorption photometry (NDUV) utilizes the electronic transitions of molecules stimulated by the absorption of radiation from some gases, as in the case of the ETG 6900 P Cl2 with chlorine.
In comparison to IR absorption, these stimulations are afflicted with higher cross-sections (→ absorption coefficient α), so that the proportion of radiation absorption is greater.
The NDUV technique is therefore particularly suitable for trace analysis in the ppm range. Furthermore, this kind of gas analysis is not influenced by interfering water vapor concentrations.
