Preparation

1. The temperature of the sample should be between 20 °C and 30 °C.

2. The analysis must take place within one hour after taking the sample at the latest.

3. With the analysis of sea water samples, before the addition of Ammonia No. 1

Tablet, twoscoops of ammonium conditioning powder must be added to the sample

and dissolved by swirling.

Remarks

1. The AMMONIA No. 1 tablet will only dissolve completely after the AMMONIA No. 2

Tablet has been added.

2. Ammonium and chloramines are accounted for in the urea determination.

Interferences

Persistant Interferences

• Concentrations above 2 mg/L urea can lead to results within the measuring range. In

this case, the water sample must be diluted with water that is free from urea and the

measurement must be repeated (plausibility test).

Removeable Interferences

• A UREA PRETREAT Tablet eliminates the interference of free chlorine up to 2 mg/L

(two tablets up to 4 mg/L, 3 tablets up to 6 mg/L).
