principle of operation

Detection method
The concentration measurement of reactive silica is based on the well documented color reaction with ammoniummolybdate.

To improve the lower limit of detection, a reducing reagent is added to convert the yellow molybdosilic acid to molybdenum blue.

In the presence of phosphate, an additional reagent is added prior to the reducing agent to remove the phosphate interference.

The analysis is batch-wise, which gives the most stable results compared with other continuous flowing systems.

Specifications are subject to change without notice.
