1. Pour a 5 mL water sample into each of the measuring glasses using the provided plastic syringe.
2. Place one measuring glass on position A in the comparator.
3. Only add the reagent to the measuring glass on position B.
4. Add 5 drops of SiO2-1 to the measuring glass on position B, seal the glass, and mix. Wait for 3 minutes.
5. Add 5 drops of SiO2-2 to the measuring glass on position B, seal the glass, and mix. Wait for 1 minute.
6. Add 5 drops of SiO2-3 to the measuring glass on position B, seal the glass, and mix.
7. Open the glass after 15 minutes and place it on position B in the comparator.
8. Slide the comparator until the colors match in the inspection hole on top. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
9. After use, rinse out both measuring glasses thoroughly and seal them.
Please note that the reagents provided in the kit are also suitable for photometric evaluation. The method can also be applied for the analysis of sea water.
