To perform a phosphate test using the MACHEREY-NAGEL 931084 VISOCOLOR ECO Phosphate Test Kit, follow these steps:

1. Pour a 5 mL water sample into each of the measuring glasses using the plastic syringe provided in the kit.
2. Place one of the measuring glasses on position A in the comparator.
3. Only add the reagent to the other measuring glass (position B).
4. Add 6 drops of PO4-1 reagent to the measuring glass at position B, seal the glass, and mix.
5. Add 6 drops of PO4-2 reagent to the same measuring glass at position B, seal the glass, and mix.
6. Open the glass after 10 minutes and place it on position B in the comparator.
7. Slide the comparator until the colors in the inspection hole on top match. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
8. After use, rinse out both measuring glasses thoroughly and seal them.

Please note that the reagents provided in the kit can also be used for photometric evaluation with the photometer PF-12 / PF-12Plus. Additionally, this technique can be used for analyzing sea water.

For disposal of the samples, refer to the safety data sheet provided in the kit or download it from www.mn-net.com/SDS.

If you encounter any interferences during the test, such as larger amounts of oxidizing reagents, H2S, heavy metals, or silica, please refer to the instructions in the manual for appropriate actions.

Remember to store the test kit in a cool (< 25 °C) and dry place to maintain its effectiveness.
