K-9003 Silica

K-9003 Silica Vacu-vials Kit was designed to obtain Silica levels from 0-10.00 ppm

Silica Information


The K-9003 Silica Kit was designed to accurately measure the levels of Silica in water from 0-10.00 ppm. K-9003 uses the Heteropoly Blue Method. CHEMetrics' test method determines molybdate reactive silica. The heteropoly blue chemistry is employed. Silica reacts with ammonium molybdate under acidic conditions to produce heteropoly acids, which are then reduced to form a blue color. Phosphate interferences are masked with the addition of citric acid. Results are expressed as ppm (mg/L) SiO2.

Silica (SiO2) is the oxide of silicon, the second most abundant element in the earth's crust. Silica is present as silicates in most natural waters. Typical concentrations lie between 1 and 30 mg/L. Higher concentrations may exist in brackish waters and brines. The silica content of water should be determined prior to its use in a variety of industrial applications. Silica can form a harmful scale on equipment and heat transfer surfaces, particularly steam turbine blades

What's included:

  • 30 Ampoules
  • 25 mL Sample Cup and Top
  • Activator Solution
  • Neutralizer Solution
  • Ampoule Blank
  • Instruction Manual


How to use:

  1. Put the Zero ampoule into the device and cover with the light shield piece to zero out the unit. (NOTE: This must be zeroed any time the unit is turned off and turned back on)
  2. Fill to the 15 mL mark in the sample cup with sample water.Fill the sample cup to 25ml
  3. Add 10 drops of Activator Solution, cap Sample Cup, and shake gently. Wait 4 minutes
  4. Add 5 drops of Neutralizer Solution, cap Sample Cup, and shake gently. Wait 1 minute.
  5. Snap the end of the Vacu-vial in the water on the bottom/side of the 25 mL sample cup.Snap the tip of the ampoule on the bottom and side of the sample cup
  6. Mix the contents of the ampoule by tipping back and forth a few times.Tip the vacu-vial back and forth to mix
  7. Dry the vacu-vial and wait 2 minutes for color development.Dry vacu-vial and then insert into the I-2019
  8. Place the vacu-vial ampoule into the device (flat end first) for readout.
