Digox 602 silica
– The determination of dissolved silicic acid (ortho-silicate) in the water-steam cycle is of great importance for the operation and plant safety in
power plants. In addition to the determination of ortho-silicate in the live
steam in order to avoid deposits or crystallisation inside the turbine, it is
possible to detect an aperture in the anion filter or mixed bed exchanger.
The Digox 602 silica is constantly being developed and is in accordance with the physical-chemical measuring method of the new VGB guidelines S-006 for the quantitative detection of dissolved silicic acid.
A photometric procedure with a detection limit of 0.5 ppb is used which is ideally suited for the determination of silicic acid in ultra pure power plant water.
