WE410

The WE410 silica analyzer employs the silicomolybdate spectrophotometric method. The principle is that under acidic conditions, the silicon in water reacts with ammonium molybdate to form yellow silicomolybdic acid, which is then reduced by a reducing agent (such as ascorbic acid) to form a deep blue silicomolybdate complex. The instrument illuminates the reaction solution with light of a specific wavelength (815 nm) and measures its absorbance to calculate the precise concentration of silica according to the Lambert-Beer law.

The WE410 Silica Analyzer is primarily used in pure water systems of thermal power plants, nuclear power stations, and large industrial boilers. It continuously monitors trace amounts of silica in boiler feedwater, steam condensate, and demineralized water to prevent silicate deposition on boiler tube walls and turbine blades under high temperature and high pressure, ensuring the safe operation of the thermal system and improving thermal efficiency.
