Answer:0.01–0.25 mg/L as Si and 0.02–0.53 mg/L as SiO₂.
Answer:The 1144100001 package is supplied for 150 tests.
Answer:Visual colorimetry based on the silicomolybdenum blue reaction.
MQuant® Silicate Test detects dissolved silicate in water by a sensitive colorimetric method. Silicate reacts with molybdate under acidic conditions, and subsequent reduction develops a blue silicomolybdate complex. The test solution is compared with a graduated visual color reference using long test tubes and a comparator. The analytical range is 0.01–0.25 mg/L as silicon, corresponding to 0.02–0.53 mg/L as SiO₂. This configuration provides 150 tests. It is particularly useful for monitoring low silicate concentrations in boiler feedwater, cooling systems, surface water, seawater, drinking water, and compatible industrial streams. Reporting the result as either Si or SiO₂ requires using the appropriate concentration scale; the two units should not be mixed during data comparison.
