The product
Digox 602 silica complies with the physicochemical measuring method of the new VGB S-006 guidelines for the quantitative detection of dissolved silicic acid. The photometric method with a detection limit of 0.5 ppb is used, which is ideal for the determination of silicic acid in ultra-pure water. To determine the measured values, the Lambert-Beer law is applied in combination with an additional calibration and calculation for the non-linear range at high concentrations.
