Silica Test Background:

Silicon is the second most abundant element in the earth's crust. By decomposition of natural rocks, silica is added to water. An adequate treatment of boiler feed water is necessary to avoid corrosion as well as sediment accumulation of the heating system, and thus maintain its durability and efficiency. However, a high content of silica can lead to acid-fixed deposits (so-called silicate stone) and thus restrict a safe, trouble-free operation. Targeted monitoring of silica concentration allows a more efficient operation and can prevent costly downtimes.

Silica 931033 & 931233 - In acidic solution soluble silica or silicates react with ammonium molybdate to form yellow silicomolybdic acid, which is reduced to silico-molybdenum blue with a reducing agent. (Reaction principle analogous to DIN EN ISO 16264-H57)
Silica HR 931234 - Photometric determination with molybdate to form yellow colored molybdosilicic acid (reaction principle is analogous to US standard methods 4500-Si D).

VISOCOLOR® ECO Range:

VISOCOLOR® ECO presents a product group of colorimetric and titrimetric test kits which avoids hazardous substances wherever possible. With VISOCOLOR® ECO even water constituents with low limiting values can be determined with sufficient accuracy. All VISOCOLOR® ECO test kits are packed in an environment-friendly box and contain easy to understand instructions in 6 languages. Many of the colorimetric tests can also be used in conjunction with the PF-3 and PF-12 photometers for photometric evaluation of results.
