Preparation

1. Cleaning of vials:

As many household cleaners (e.g. dishwasher detergent) contain reducing

substances, the subsequent determination of oxidising agents (e.g. ozone and

chlorine) may show lower results. 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. When preparing the sample, Bromine outgassing, e.g. through the pipette or shaking,

must be avoided. The analysis must take place immediately after taking the sample.

3. Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7

before the analysis (use 0.5 mol/l Sulphuric acid or 1 mol/l Sodium hydroxide).

Interferences

Persistant Interferences

1. All oxidising agents in the samples react like bromine, which leads to higher results.

2. Concentrations above 22 mg/L Bromine can lead to results within the measuring

range of up to 0 mg/L. In this case, the water sample must be diluted. 10 ml of the

diluted sample should be mixed with the reagent and the measurement taken again

(plausibility test).

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).

Sampling

1. When preparing the sample, 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

dioxide. 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. Strong alkaline or acidic water samples must 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).

Sampling

1. Samples are to be collected in clean glass or plastic bottles. These should have been

cleaned with 6 N (1:1) Hydrochloric acid and then rinsed with deionised water.

2. To preserve samples for later analysis, the pH value of the sample must be adjusted

to less than 2. Approximately 2 ml per litre of concentrated Hydrochloric acid can be

added to the sample. the sample is tested immediately, this addition is not necessary.

3. If determination of dissolved Iron is required, the sample must be filtered through a

0.45-micron filter or equivalent medium immediately after it has been collected and

before acidification.

4. Preserved samples should be stored no longer than 6 months at room temperature.

5. The pH is to be adjusted to 3–5 by adding 5 N Sodium hydroxide solution before the

analysis. A pH value of 5 must not be exceeded, since this can lead to precipitation of

iron.

6. The test result needs to be corrected on the basis of the volume additions.

Preparation

1. All glassware is to be cleaned with cleaning detergents and then rinsed with tap

water. Afterwards, it should be reclaimed with Hydrochloric acid (1:1) and deionised

water. These steps will remove any deposits that may cause slightly higher results.

2. If the sample contains 100 mg/L or more Molybdate (MoO4 2-) then the sample reading

must be taken immediately after zeroing the device.

3. For more accurate results, a reagent blank value can be determined for each new

batch of reagent. Follow the procedure set out, using deionised water instead of the

sample. The measured value that is obtained should be /subtracted from the readings

of these results.

Notes

1. A blue colour develops in the presence of iron. A small amount of undissolved

powder has no influence on the result.

Interferences

Removeable Interferences

1. PH interference: A sample pH after the addition of reagent, which is less than 3 or

greater than 4, may inhibit colour formation since the developed colour fades too

quickly, or can result in turbidity. This means that the pH value must be adjusted to

between 3 and 5 in the measuring glass before the addition of the reagent:

A suitable amount of iron-free acid or base, such as 1 N Sulphuric acid or 1 N

Sodium hydroxide, can be added on a drop by drop basis.

A volume correction must be carried out if significant volumes of acid or base are

added.

Preparation

1. If there are strong complexing agents in the sample, the response time must be

extended until no further colour development is seen. However, very strong iron

complexes are not included in the measurement. In this event, the complexing agent

must be destroyed by means of oxidation with acid/persulphate and the sample also

neutralised to pH 6–9.

2. For the measurement of total iron, both suspended and dissolved, the sample must

be boiled with acid/persulphate. It must be neutralised back to pH 6–9 and refilled to

the original volume with deionised water.

Digestion

Total iron consists of suspended, soluble and complexed iron. The sample must be not

filtered before measuring. To ensure homogenisation of the sample, deposed particles

must be evenly distributed immediately prior to sampling by forcible shaking. A filtration

of the sample is necessary for the determination of total soluble iron (including the

complex iron compounds).The equipment required for the determination of total iron and

reagents are not included in the standard delivery.

Persistant Interferences

1. All oxidising agents in the samples react like chlorine, which leads to higher results.

2. Concentrations above 6 mg/L Ozone can lead to results within the measuring

range of up to 0 mg/L. In this case, the water sample must be diluted. 10 ml of the

diluted sample should be mixed with the reagent and the measurement taken again

(plausibility test).

KS336-Propan-2-ol, 65 mL 65 mL 56L033665

Preparation

•Preparing the cartridge:

1. Remove the plunger from a suitable syringe. Attach the C18 cartridge to the syringe

cylinder.

2. Add 5 ml of KS336 (propane-2-ol) to the syringe cylinder.

3. Using the plunger, press the solvent by drop through the cartridge.

4. Remove the solvent that has passed through.

5. Remove the plunger again. Fill the syringe cylinder with 20 ml of deionised water.

6. With the help of the plunger, press the contents through the cartridge drop by drop.

7. Discard the deionised water that has flowed through.

8. The cartridge is now ready for use.

Notes

1. If little or no turbidity is present at correct dose concentrations, the sample will need a

pre-concentration step in order to detect this level of polyacrylate/polymer.

2. Anomalous results occur when interferences are present as part of the sample

components or from sample contaminants. In this case, the interference will need to

be eliminated.

3. This test has been calibrated using polyacrylic acid 2'100 sodium salt in the range

1-30 mg/L. Other polyacrylates/polymers will give differing responses and therefore

the test range will vary.

Vorbereitung

1. Reinigung der Küvetten:

Da viele Haushaltsreiniger (z.B. Geschirrspülmittel) reduzierende Stoffe enthalten,

kann es bei der nachfolgenden Bestimmung von Oxidationsmitteln (z.B. Ozon, Chlor)

zu Minderbefunden kommen. Um diesen Messfehler auszuschließen, sollten die

Glasgeräte chlorzehrungsfrei sein. Dazu weden die Glasgeräte für eine Stunde unter

Natriumhypochloritlösung (0,1 g/L) aufbewahrt und danach gründlich mit VE-Wasser

gespült.

2. Bei der Probenvorbereitung muss das Ausgasen von Brom, z.B. durch Pipettieren

und Schütteln vermieden werden. Die Analyse muss unmittelbar nach der

Probennahme erfolgen.

3. Stark alkalische oder saure Wässer müssen vor der Analyse in einen pH-Bereich

zwischen 6 und 7 gebracht werden (mit 0,5 mol/l Schwefelsäure bzw. 1 mol/l

Natronlauge).

Probenahme

1. Bei der Probenvorbereitung muss das Ausgasen von Chlor, z.B. durch Pipettieren

und Schütteln, vermieden werden.

2. Die Analyse muss unmittelbar nach der Probenahme erfolgen.

Vorbereitung

1. Reinigung der Küvetten:

Da viele Haushaltsreiniger (z.B. Geschirrspülmittel) reduzierende Stoffe enthalten,

kann es bei der Bestimmung von Chlor zu Minderbefunden kommen. Um diesen

Messfehler auszuschließen, sollten die Glasgeräte chlorzehrungsfrei sein. Dazu

werden die Glasgeräte für eine Stunde unter Natriumhypochloritlösung (0,1 g/L)

aufbewahrt und danach gründlich mit VE-Wasser (Vollentsalztes Wasser) gespült.

2. Für die Einzelbestimmung von freiem Chlor und Gesamtchlor ist es sinnvoll, jeweils

einen eigenen Satz Küvetten zu verwenden (siehe EN ISO 7393-2, Abs. 5.3).

3. Die DPD-Farbentwicklung erfolgt bei einem pH-Wert von 6,2 bis 6,5. Die

Reagenzien enthalten daher einen Puffer zur pH-Wert Einstellung. Stark alkalische

oder saure Wässer müssen jedoch vor der Analyse in einen pH-Bereich zwischen 6

und 7 gebracht werden (mit 0,5 mol/LSchwefelsäure bzw. 1 mol/LNatronlauge).

Anmerkungen

1. Evo-Tabletten können alternativ zu der entsprechenden Standard-Tablette

verwendet werden (z.B. DPD Nr. 3 Evo anstatt DPD Nr. 3).

Störungen

Permanente Störungen

• Alle in den Proben vorhandenen Oxidationsmittel reagieren wie Chlor, was zu

Mehrbefunden führt.

Ausschließbare Störungen

• Störungen durch Kupfer und Eisen(III) sind durch EDTA zu beseitigen.

• Bei Proben mit hohem Calciumgehalt* und/oder hoher Leitfähigkeit* kann es

bei der Verwendung der Reagenztabletten zu einer Eintrübung der Probe und

damit verbundener Fehlmessung kommen. In diesem Fall sind alternativ die

Reagenztablette DPD No. 1 High Calcium und die Reagenztablette DPD No. 3 High

Calcium zu verwenden.

*exakte Werte können nicht angegeben werden, da die Entstehung einer Trübung

von Art und Zusammensetzung des Probenwassers abhängt.

• Konzentrationen über 10 mg/L Chlor, bei Verwendung von Tabletten, können

zu Ergebnissen innerhalb des Messbereichs bis hin zu 0 mg/L führen. Bei einer

zu hohen Chlorkonzentration muss die Probe mit chlorfreiem Wasser verdünnt

werden. 10 mLder verdünnten Probe werden mit Reagenz versetzt und die Messung

wiederholt (Plausibilitätstest).
