EDK 6900S-Cl online Cl2 analyzer

Overview 

Chlor-alkali process is an industrial process for electrolysis of sodium chloride. It is used in the production of chlorine and sodium hydroxide (alkali/caustic soda), both of which are essential and commonly used chemicals in industry.

Etg6900s-cl was used to analyze Cl2 in hydrogen based on nondispersive ultraviolet absorption spectroscopy (NDUV).  NDUV nondispersive ultraviolet absorption spectroscopy is a common method to determine the concentration of complex gas mixtures. The gas analyzer uses modern optical elements to optimize the results of the analyzer. We used a special LED technology to get a steady emission of radiation. This leads to a high-resolution gas analysis system that can detect changes in gas concentrations below 1ppm.

Nondispersive ultraviolet absorption spectrometry (NDUV) uses the principle that the electrons of a particular gas molecule absorb radiation and then undergo a stimulated transition. Compared with the infrared absorption method, these excitations are affected by a larger cross-section (the absorption coefficient), so the proportion of radiation absorption will be larger. Therefore, NDUV method is particularly suitable for PPM trace gas analysis. In addition, the gas analysis method is not affected by the concentration of interfering water vapor.

ETG 6900 software  

The program can achieve data storage, chart display, analysis report, real-time detection, data export and other functions; The origin of the time axis can be adjusted to coincide with the start time of measurement, or automatically adapt to the change of the horizontal and vertical axes. The user can see the real-time update of the analysis data in the window. Any existing alerts with reference code are also displayed on the same screen as the software.
