2029 Silica Process Analyzer

From Metrohm Process Analytics

Silica is used in a variety of applications, from microelectronics (in wafer production) to components used in the food industry.

In the power industry, Si is not held in such high regard and is considered a major impurity, responsible for boiler scale and deposits on steam turbine blades. Due to increasing industry demands for more efficient energy production as well as the increase in operating pressures in modern boilers, the necessity to measure and control Si concentrations is more crucial than ever. Silica also plays an important process control role at the demineralization plant where demi-water is produced and polished from groundwater or surface water.

Because of its role in many different (production) processes, it is of vital importance to closely monitor the concentration. The 2029 Silica process analyzer from Metrohm Process Analytics is the most straightforward and easy-to-use tool to do so online.

About the Silica application

Soluble silica (Si4+) is determined photometrical y on the 2029 Process Photometer with the molybdenum blue method, ranging from µg/L to mg/L.
