The formulation of the VISOCOLOR Powder Pillows Ammonium has changed. With the new formulation we could drastically enhance the tolerance of the test kit towards carbonates while reducing the reaction time from 30 to 15 minutes.
Together with the new formulation there is also an additional reagent available which allows the determination of ammonium in sea water.
A photometer update is not necessary, the calibration has been retained.
