Sampling
1. When preparing the sample, chlorine outgassing, e.g. through the pipette or shaking,
must be avoided.
2. The analysis must take place immediately after taking the sample.
Preparation
1. Cleaning of vials:
As many household cleaners (e.g. dishwasher detergent) contain reducing
substances, this can lead to lower results with the determination of chlorine. To avoid
measurement errors, the glassware used should be free of chlorine consumption. To
achieve this, all glassware should be placed in a sodium hypochlorite solution (0.1 g/
L) for one hour and then rinsed thoroughly with deionised water.
2. For individual testing of free and total chlorine, the use of different sets of glassware
is recommended (EN ISO 7393-2, 5.3)
3. The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagents
therefore contain a buffer for the pH adjustment. Strong alkaline or acidic water
samples must therefore be adjusted between pH 6 and pH 7 before the analysis (use
0.5 mol/Lsulphuric acid or 1 mol/Lsodium hydroxide).
Notes
1. Evotablets can be used as an alternative to the corresponding standard tablet (e.g.
DPD No.3 Evoinstead of DPD No.3).

Interferences
Persistant Interferences
All oxidising agents in the samples react like chlorine, which leads to higher results.
Removeable Interferences
Interference from copper and iron (III) are eliminated by the addition of EDTA.
The use of reagent tablets in samples with high calcium content* and/or
high conductivity* can lead to turbidity of the sample and therefore incorrect
measurements. In this case, the alternative reagent tablet DPD No.1 High Calcium
and reagent tablet DPD No.3 High Calcium should be used.
*it is not possible to give exact values, because the development of turbidity depends
on the composition and nature of the sample.
Concentrations above 10 mg/L chlorine, in the event of using fluid reagents, can
lead to results within the measuring range of up to 0 mg/L. In the event of a high
concentration of chlorine, the sample must be diluted with chlorine-free water. 10
mLof the diluted sample should be mixed with the reagent and the measurement
taken again (plausibility test).
