1.1 Methods

The precision of Lovibond® Reagent Systems (tablets, powder packs and tube tests) is identical to the precision speciﬁed in standards literature such as American Standards (AWWA), ISO etc.

Most of the data referred to in these standard methods relates to Standard Solutions. Therefore they are not readily applicable to drinking-, boiler- or waste-water, since various interferences can have a major inﬂuence on the accuracy of the method. For this reason we don’t state such potentially misleading data.

Due to the fact that each sample is different, the only way to check the tolerances (‘precision’) is the Standard Additions Method.

According to this method, ﬁrst the original sample is tested. Then further samples (2 to 4) are taken and small amounts of a Standard Solution are added, and further results are obtained. The amounts added range from approximately half, up to double the amount present in the sample itself.

These supplementary results make it possible to estimate the actual concentration of the original sample by comparison.

Literature

The reagent formulations are based on internationally recognised test methods. Some are described in national and/or international guidelines.

PM600_1c 03/2013

1.1 Methods

Notes:

Vial cleaning: 1. As many household cleaners (e.g. dishwasher detergent) contain reducing substances,the subsequent determination of Bromine may show lower results. To avoid any measurement errors, only use glassware free of Chlorine demand. Preparation: Put all applicable glassware into Sodium hypochlorite solution (0.1 g/l) forone hour, then rinse all glassware thoroughly with deionised water.

Preparing the sample: 2. When preparing the sample, the lost of Bromine, e.g. by pipetting or shaking, must be avoided. The analysis must take place immediately after taking the sample.

The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagent 3. tablet therefore contains a buffer for the pH adjustment. Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7 before the reagent is added (use 0.5 mol/l Sulfuric acid resp. 1 mol/l Sodium hydroxide).

Exceeding the measuring range: 4. Concentrations above 22 mg/l Bromine can lead to results showing 0 mg/l. In this case, the water sample must be diluted with water free of Bromine. 10 ml of the diluted sample should be mixed with the reagent and the measurement repeated.

Oxidising agents such as Chlorine, Ozone etc. interfere as they react in the same way as 5. Bromine.

1.1 Methods

Notes:

Vial cleaning: 1. As many household cleaners (e.g. dishwasher detergent) contain reducing substances, the subsequent determination of Chlorine may show lower results. To avoid any measurement errors, only use glassware free of Chlorine demand. Preparation: Put all applicable glassware into Sodium hypochlorite solution (0.1 g/l) for one hour, then rinse all glassware thoroughly with deionised water.

For individual testing of free and total Chlorine, the use of different sets of glassware is 2. recommended (EN ISO 7393-2, 5.3)

Preparing the sample: 3. When preparing the sample, the lost of Chlorine, e.g. by pipetting or shaking, must be avoided. The analysis must take place immediately after taking the sample.

The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagents 4. therefore contain a buffer for the pH adjustment. Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7 before the reagent is added (use 0.5 mol/l Sulfuric acid resp. 1 mol/l Sodium hydroxide).

Exceeding the measuring range: 5. Concentrations above: 10 mg/l Chlorine using tablets (method 100) can lead to results showing 0 mg/l. In this case, the water sample must be diluted with water free of Chlorine. 10 ml of the diluted sample should be mixed with the reagent and the measurement repeated.

Turbidity (can lead to errors): 6. The use of the DPD No. 1 tablet (method 100) in samples with high Calcium ion contents* and/or high conductivity* can lead to turbidity of the sample and therefore incorrect measurements. In this case, the reagent tablet DPD No. 1 High Calcium should be used as an alternative. If turbidity does occur after the DPD No. 3 tablet has been added, this can be prevented by using the DPD No. 1 HIGH CALCIUM tablet and the DPD No.3 High Calcium tablet. The DPD No. 1 High Calcium should only be used in combination with the DPD No.3 High Calcium.

* it is not possible to give exact values, because the development of turbidity depends on the nature of the sample.

Notes:

1. To optimise the readings an optional batch related calibration can be performed using Mode 40, see page 76.

2. Strong alkaline or acidic water samples must be adjusted to a pH-value between pH 4 and 10 before the tablets are added (use 1 mol/l Hydrochloride acid resp. 1 mol/l Sodium hydroxide).

3. For accurate test results exactly 10 ml of water sample must be taken for the test.

4. This method was developed from a volumetric procedure for the determination of Calcium Hardness. Due to undeﬁned conditions, the deviations from the standardised method may be greater.

5. The tolerance of the method is increasing with higher concentrations. When diluting samples, this should be taken in account, always measuring in the ﬁrst third of the range.

Notes:

Digestion procedure for the determination of total dissolved and undissolved iron.

Add 1 ml of concentrated sulfuric acid to 100 ml water sample. Heat and boil for 10 1. minutes or until all particles are dissolved. After cooling down, the sample is set to a pH-value of 3 to 6 by using ammonia solution. Reﬁll with deionised water to the previous volume of 100 ml and mix well. 10 ml of this pre-treated solution is used for the following analysis. Perform as described by the selected test method.

Water which has been treated with organic compounds like corrosion inhibitors must 2. be oxidised where necessary to break down the iron. Therefore add 1 ml concentrated sulfuric acid and 1 ml concentrated nitric acid to 100 ml water sample and boil to approx. half volume. After cooling down, proceed as described above.

1.1 Methods

Notes:

Vial cleaning: 1. As many household cleaners (e.g. dishwasher detergent) contain reducing substances, the subsequent determination of Ozone may show lower results. To avoid any measurement errors, only use glassware free of Chlorine demand. Preparation: Put all applicable glassware into Sodium hypochlorite solution (0.1 g/l) for one hour, then rinse all glassware thoroughly with deionised water.

Preparing the sample: 2. When preparing the sample, the lost of Ozone, e.g. by pipetting or shaking, must be avoided. The analysis must take place immediately after taking the sample.

The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagent 3. tablet therefore contains a buffer for the pH adjustment. Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7 before the tablet is added (use 0.5 mol/l Sulfuric acid resp. 1 mol/l Sodium hydroxide).

Exceeding the measuring range: 4. Concentrations above 6 mg/l Ozone can lead to results showing 0 mg/l. In this case, the water sample must be diluted with water free of Ozone. 10 ml of the diluted sample should be mixed with the reagent and the measurement repeated.

1.2.1 Correct use of reagents

The reagents must be added in the correct sequence.

Tablet reagents:

The tablet reagents should be added to the water sample straight from the foil without touching them with the ﬁngers.

1.2.2 Cleaning of vials and accessories for analysis

Vials, caps and stirring rods should be cleaned thoroughly after each analysis to prevent interferences.

Procedure:

Clean vials and accessories after each analysis as soon as possible.

a. Clean vials and accessories with laboratory detergent (e.g. Extran® MA 02 (neutral, phosphatic), Extran® MA 03 (alkaline, phosphate-free) from Merck KGaA).

b. Rinse thoroughly with tap water. c. On demand (see Notes) perform special cleaning as required, e.g.: rinse with diluted

Hydrochloric acid solution. d. Rinse thoroughly with deionised water.

1.2.3 Guidelines for photometric measurements

Vials, caps and stirring rods should be cleaned thoroughly after each analysis to prevent 1. interferences. Even minor reagent residues can cause errors in the test result.

The outside of the vial must be clean and dry before starting the analysis. Clean the outside 2. of the vials with a towel. Fingerprints or other marks will be removed.

If there is no deﬁned vial for the blank, the zeroing and the test must be carried out with 3. the same vial as there may be slight differences in optical performance between vials.

The vials must be positioned in the sample chamber for zeroing and test with the 4.

intervals and – if necessary – clean the light entry surfaces of the sample chamber using a moist cloth or cotton buds.

Large temperature differences between the instrument and the environment can lead to 9. errors – e.g. due to the formation of condensation in the area of the lens or on the vial.

To avoid errors caused by stray light do not use the instrument in bright sunlight.10.

Pipette the required volume of the diluted sample into the vial and proceed as described in the test methods.

Caution:

1. Dilution decreases accuracy.

2. Do not dilute water samples for measurement of pH-values. This will lead to incorrect test results. If “Overrange” is displayed use another instrument (e.g. pH-meter).

1.2.5 Correcting for volume additions

If a larger volume of acid or base is used to pre-adjust the pH-value, a volume correction of the displayed result is necessary.

Example:

For adjusting the pH-value of a 100 ml water sample 5 ml of acid had to be added. The corresponding displayed result is 10 mg/l.

Total volume = 100 ml + 5 ml = 105 ml

Correction factor = 105 ml / 100 ml = 1.05

Corrected result = 10 mg/l x 1.05 = 10.5 mg/l

2.3.5 Performing Tests

When zero calibration is complete, remove the vial from the sample chamber and perform the tests as described under “Method“.

When the results have been displayed:

- with some methods you can change between different chemical species

- you can store and/or print out the results

- perform further analysis with the same zero

- select a new method

2.3.6 Ensuring reaction periods (countdown)

To ensure compliance with reaction periods a time delay is incorporated: the countdown. There are two kinds of countdowns:

 •Press[ ] key. Prepare water sample, start countdown with [ ] key and proceed as described in the mode description. The vial must not be placed in the sample chamber.

 •Press[TEST]key. Prepare the water sample as described in the method description and place the vial in the sample chamber. The display shows the countdown by pressing the [TEST] key and the countdown is started automatically. After the reaction period is ﬁnished the measurement starts automatically.

Notes:

1. It is possible to ﬁnish the working countdown by pressing the [

] key. Reading starts immediately. In this case the operator is responsible for ensuring the necessary reaction period. Non-compliance with reaction periods leads to incorrect test results.

2. The time remaining is displayed continuously. The beeper indicates the last 10 seconds.

2.3.7 Changing chemical species

For some methods there is a possibility to change the chemical species of the test result. If the test result is displayed press arrow key [ ] or [ ].

Example:

319 Phosphate LR T

-----[ ]----> 319 Phosphate LR T <---- [ ] ----- 319 Phosphate LR T

0.05-4 mg/l PO4 0.02-1.3 mg/l P 0.04-3 mg/l P2O

<---- [ ] ----- ------ [ ] ---->

1.00 mg/l PO4 0.33 mg/l P 0.75 mg/l P2O

If the species of a test result is changed the displayed range is adjusted automatically. For an already stored result it is not possible to change the chemical species. The last displayed chemical species is kept by the instrument and will be displayed if this method is used the next time. If there is the possibility to change the chemical species for a method it is described in the manual. The arrows indicate the possible chemical species and are printed below the notes of the method:

One Time Zero (OTZ)

OneTimeZero is available for all methods where Zero is performed in a 24 mm Ø round vial with sample water (see chapter 1.1 Table of Methods).

OneTimeZero can be used for different tests providing the tests are performed with the same sample water and under the same test conditions. When changing the method, it is not necessary to perform a new Zero. The test can be carried out straight away.

When the instrument is ﬁrst being used for an OTZ compatible method and OneTimeZero is activated, the instrument will request a new Zero with “prepare OT-Zero”. Perform Zero as described in the method. This Zero will be stored and used for all methods with OTZ function until the instrument is switched off.

If necessary, a new Zero can be performed by pressing [Zero] key at any time.

Switching the “OTZ-Function“ on and off:
