Test Papers for Qualitative determinations of Metals and Metal Compounds

July 2020

NANOCOLOR Potassium 50 (REF 985045) has been improved. The change is introduced from LOT 45004, which is available from stock as of 20th July 2020.

The test is now produced with an integrated ammonium compensation. The modified recipe allows a simple determination of potassium in the presence of an ammonium interference up to a concentration of 200 mg/L NH4-N, which is unique in the market.

The use of the additional ammonium compensation reagent (REF 918045) is therefore no longer necessary. Additional information on this topic will be part of our upcoming water news mailing.

Please note, that the test procedure has changed.

An update of the photometers is not required.
