A Wet chemistry Analyzer for measuring Concentration of Ammonia in Water
following the colorimetric detection via Salicylate method.
Applications
The ChemMIT W3107SY Ammonia Analyzer is specialized in detecting the ammonia concentration in the wastewater from industries, particularly the petroleum refinery industries.
Principle of Operation
The principle of Ammonia analyzer is based of US EPA Method 350.1. Ammonia reacts with salicylate and hypochloride ions, giving a green color solution which color is proportional to the concentration of the ammonia ion. The color is detected by measuring the increase in absorption at a specific wavelength. ChemMIT W3107SY Ammonia Analyzer is designed with a photometer to accurately detect the presence of ammonia ions in the solution. To avoid interferences, ChemMIT W3107SY uses a stabilizer to enhance the accuracy and precision of the results.
The reagents are delivered by peristaltic pumps, which accurately transfer each reagent to the reactor. With a user programmable reaction time, ammonia analyzer provides a fast, efficient way to detect the concentration of ammonia nitrogen level in drinking or effluent water.
