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. 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.

1.1 Methods

Notes:

1. Vial cleaning: 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.

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. Preparing the sample: 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.

4. 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 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).

5. Exceeding the measuring range: Concentrations above: 10 mg/l Chlorine using tablets 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.

6. Turbidity (can lead to errors): The use of the DPD No. 1 tablet in samples with high Calcium ion content* 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.

7. combined Chlorine = total Chlorine – free Chlorine

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

1.1 Methods

Notes:

1. For photometric determination of pH values only use PHENOL RED tablets in black printed foil pack and marked with PHOTOMETER.

2. Water samples with low values of Alkalinity-m (below 35 mg/l CaCO3) may give wrong pH readings.

3. pH values below 6.5 and above 8.4 can produce results inside the measuring range. A plausibility test (pH-meter) is recommended.

4. The accuracy of the colorimetric determination of pH values depends on various boundary conditions (buffer capacity of the sample, salt content etc.).

5. Salt error Correction of test results (average values) for samples with salt content of:

Indicator Salt content

Phenol red 1 molar 2 molar 3 molar

1.1 Methods

Notes:

1. To optimise the readings an optional batch related calibration can be performed using Mode 40, see page 58.

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.

6. Interferences:

• Magnesium hardness up to 200 mg/l CaCO3 does not interfere.

• Iron concentration above 10 mg/l may cause low results.

• Zinc concentration above 5 mg/l may cause high results.

1.1 Methods

Notes:

1. Vial cleaning: 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) for one hour, then rinse all glassware thoroughly with deionised water.

2. Preparing the sample: 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.

3. The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagent 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).

4. Exceeding the measuring range: 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 Bromine.

4. Turbidity (can lead to errors): The use of the DPD No. 1 tablet in samples with high Calcium ion content* and/or high conductivity* can lead to turbidity of the sample and therefore incorrect measurements.

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

5. Exceeding of the measuring range: 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.

Water Balance (Langelier Saturation Index)

When water is in balance, it is said to be neither corrosive nor scale-forming. In other words, it will not deposit a layer of calcium scale neither will it dissolve an existing layer of scale.

For Langelier calculation the following tests are required:

• pH Value

• Temperature

• Calcium hardness

• Total Alkalinity

• TDS (Total Dissolved Solids) Run each test separately and note the results.

Calculate the Langelier Saturation Index as described below:

Guidelines for photometric measurements

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

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

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

4. The vials must be positioned in the sample chamber for zeroing and test with the mark on the vial aligned with the mark on the instrument.

5. Always perform zeroing and test with closed vial cap. Only use cap with sealing ring.

6. Bubbles on the inside of the vial may also lead to errors. To prevent this, remove the bubbles by swirling the vial before performing the test.

7. Avoid spillage of water in the sample chamber. If water should leak into the instrument housing, it can destroy electronic components and cause corrosion.

8. Contamination of the lens in the sample chamber can result in errors. Check at regular intervals and – if necessary – clean the light entry surfaces of the sample chamber using a moist cloth or cotton buds.

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

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

User Calibration

If a test method is user calibrated the method name is displayed inverse.

Procedure:

• Prepare a standard of known concentration and use this standard instead of the sample according to the test procedure.

• It is recommend to use well known standards which are formulated according to DIN EN, ASTM or other international norms or to use certiﬁed standards which are commercially available.

• After measuring this standard solution it is possible to change the displayed results to the required value.

• If a method uses a mathematic equation for the calculation of the result, it is only possible to calibrate the basic tests since all the other tests use the same polynomial.

• The same applies for some test procedures which use a polynomial from another test procedure.

Return to factory calibration: If the user calibration is deleted the factory calibration is automatically activated.
