Sodium Analyzer
Model NA-600
The Sodium Analyzer is an on-line sequential sampling analyzer, a sequence of sampling, analysis and result processing is performed and repeated using colorimetric methods. The measurement is a colorimetric analysis using an LED light source and a heated colorimetric cell designed for measuring trace amounts of analyse in water.
The colorimetric analyzer is assembled with two separated sections. The bottom section is the LIQUIDS section. It includes all of the components involved in the flow, mixing and reaction stages of the sample and reagents. Numerous analysis configurations can be programmed, depending on accessories and of the number of micro pumps mounted in the Liquid Section. The top section is the ELECTONICS enclosure. It includes the main power supply, the controller PCB assembly and the touch screen interface.
The measuring Principle
The sodium measurement is based on the proven accuracy of the glass sodium electrode for the online potentiometry detection of low ppb traces of sodium. The sodium sensor develops a potential proportional to the log of the sodium concentration, after the pH of the sample is raised to 11 to eliminate pH and ammonium interferences. This is obtained using reagent vapour addition
