PRECISION AND ACCURACY

Absorption of light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance, some of the radiation may be absorbed by atoms, molecules or crystal lattices.

If pure absorption occurs, the fraction of light absorbed depends both on the optical path length through the matter and on the physical-chemical characteristics of substance according to the Lambert-Beer Law:

-log I/Io = ελ c d

A = ελ c d

Where:

-log I/I

Therefore, the concentration "c" can be calculated from the absorbance of the substance as the other factors are known.

Photometric chemical analysis is based on the possibility to develop an absorbing compound from a specific chemical reaction between sample and reagents. Given that the absorption of a compound strictly depends on the wavelength of the incident light beam, a narrow spectral bandwidth should be selected as well as a proper central wavelength to optimize measurements.

The optical system of HI 83200 is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

Five measuring channels allow a wide range of tests.

= Absorbance (A)

Io= intensity of incident light beam I = intensity of light beam after absorption

ελ= molar extinction coefficient at wavelength λ

c = molar concentration of the substance d = optical path through the substance

Precision is how closely repeated measurements agree with each other. Precision is usually expressed as standard deviation (SD).

Accuracy is defined as the nearness of a test result to the true value.

Although good precision suggests good accuracy, precise results can be inaccurate. The figure explains these definitions.

For each method, the accuracy is expressed in the related measurement section.

Instrument block diagram (optical layout)

A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed through the sample contained in the cuvette. The optical path is fixed by the diameter of the cuvette. Then the light is spectrally filtered to a narrow spectral bandwidth, to obtain a light beam of intensity Io or I.

The photoelectric cell collects the radiation I that is not absorbed by the sample and converts it into an electric current, producing a potential in the mV range.

The microprocessor uses this potential to convert the incoming value into the desired measuring unit and to display it on the LCD.

SETUP

The measurement process is carried out in two phases: first the meter is zeroed and then the actual measurement is performed.

The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both the measurement and the calibration (zeroing) cuvette are optically identical to provide the same measurement conditions. Most methods use the same cuvette for both, so it is important that measurements are taken at the same optical point. The instrument and the cuvette cap have special marks that must be aligned in order to obtain better reproducibility.

The surface of the cuvette must be clean and not scratched. This is to avoid measurement interference due to unwanted reflection and absorption of light. It is recommended not to touch the cuvette walls with hands. Furthermore, in order to maintain the same conditions during the zeroing and the measurement phases, it is necessary to cap the cuvette to prevent any contamination.

TIPS FOR AN ACCURATE MEASUREMENT

The instructions listed below should be carefully followed during testing to ensure most accurate results.

• Color or suspended matter in large amounts may cause interference, and should be removed by treatment with active carbon and filtration: refere to Sample Preparation Chapter (page 17).

• Ensure the cuvette is filled correctly: the liquid in the cuvette forms a convexity on the top; the bottom of this convexity must be at the same level as the 10 mL mark.

COLLECTING AND MEASURING SAMPLES

• In order to measure exactly 0.5 mL of reagent with the 1 mL syringe: (a) push the plunger completely into the syringe and insert the tip into the solution. (b) pull the plunger up until the lower edge of the seal is exactly on the 0.0 mL mark. (c) take out the syringe and clean the outside of the syringe tip. Be sure that no drops are hanging

on the tip of the syringe, if so eliminate them. Then, keeping the syringe in vertical position above the cuvette, push the plunger down into the syringe until the lower edge of the seal is exactly on the 0.5 mL mark. Now the exact amount of 0.5 mL has been added to the cuvette, even if the tip still contains some solution.

• Proper use of the powder reagent packet: (a) use scissors to open the powder packet; (b) push the edges of the packet to form a spout; (c) pour out the content of the packet.

USING CUVETTES

• Proper mixing is very important for reproducibility of the measurements. The right way of mixing a cuvette is specified for each method in the related chapter.

(a) invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position. Turn

the cuvette upside-down and wait for all of the solution to flow to the cap end, then return the cuvette to the upright vertical position and wait for all of the solution to flow to the cuvette bottom. This is one inversion. The correct speed for this mixing technique is 10-15 complete inversions in 30 seconds.

This mixing technique is indicated with “invert to mix” and the following icon:

(c)(a) (b)

USING LIQUID AND POWDER REAGENTS

• Proper use of the dropper: (a) for reproducible results, tap the dropper on the table for several times and wipe the outside of the

dropper tip with a cloth.

(b) always keep the dropper bottle in a vertical position while dosing the reagent.

(a) (b)

8 9

(b) shaking the cuvette, moving the cuvette up and down. The movement may be gentle or vigorous.

This mixing method is indicated with “shake gently” or “shake vigorously”, and one of the following icons:

shake gently shake vigorously

• Pay attention to push the cuvette completely down in the holder and to align the white point on the cap to the indexing mark on the meter.

• In order to avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic

stopper and then the black cap.

• Each time the cuvette is used, the cap must be tightened to the same degree.

• Whenever the cuvette is placed into the measurement cell, it must be dry outside, and free of fingerprints, oil or dirt. Wipe it thoroughly with HI 731318 or a lint-free cloth prior to insertion.

• Shaking the cuvette can generate bubbles in the sample, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.

• Do not let the reacted sample stand too long after reagent is added. For best accuracy, respect the timings described in each specific method.

• It is possible to take multiple readings in a row, but it is recommended to take a new zero reading for each sample and to use the same cuvette for zeroing and measurement when possible (for most precise results follow the measurement procedures carefully).

• Discard the sample immediately after the reading is taken, or the glass might become permanently stained.

• All the reaction times reported in this manual are at 25 °C (77 °F). In general, the reaction time should be increased for temperatures lower than 20 °C (68 °F), and decreased for temperatures higher than 25 °C (77 °F).

INTERFERENCES

• In the method measurement section the most common interferences that may be present in an average sample matrix have been reported. It may be that for a particular treatment process other compounds do interfere with the method of analysis.

HEALTH & SAFETY

• The chemicals contained in the reagent kits may be hazardous if improperly handled.

• Read the Material Safety Data Sheet (MSDS) before performing tests.

• Safety equipment: Wear suitable eye protection and clothing when required, and follow instructions carefully.

• Reagent spills: If a reagent spill occurs, wipe up immediately and rinse with plenty of water. If reagent contacts skin, rinse the affected area thoroughly with water. Avoid breathing released vapors.

• Waste disposal: for proper disposal of reagent kits and reacted samples, refer to the Material Safety Data Sheet (MSDS).

SAMPLE PREPARATION

SAMPLE PREPARATION PROCEDURE

The following Sample Preparation Procedure applies in case of:

• Samples with color or suspended matter (turbidity).

• Concentrated samples, for which the analysis result is over the range of the parameter. Use the accessories contained in the Sample Preparation Kit to prepare the sample according to the

following instructions.

COLORED OR TURBID SAMPLES:

Colored or suspended matter in large amounts may cause interference. They should be removed by treatment with active carbon and filtration.

• If the water sample contains suspended matter, let it stand in a beaker until most of the solid particles have settled. Then, use the pipette to transfer the supernatant solution to the other beaker. To prevent the displacement of the settled solids at the bottom of the beaker, do not induce air bubbles into the solution.

• Measure 100 mL of sample with the graduated cylinder.

• If the solution still contains some turbidity or color, pour it in the large 170 mL beaker and add a powder packet of active carbon.

To access the help screens press HELP. The instrument will display additional information related to the current screen. To read all the available information, scroll the text using the s t keys. Press the Support key to access a screen with Hanna service centers and their contact details. Press the Accessories key to access a list of instrument reagents and accessories. To exit support or accessories screens press ESC and the instrument will return to the previous help screen. To exit help mode press the HELP or ESC key again and the meter will return to the previously selected screen.

• Mix well using the spoon and then wait for 5 minutes.

• Unscrew the filter assembly, put a filter disc inside and close it.

filter disc

• Connect the filter assembly to the 60 mL syringe by the screw rim.

• Remove the syringe plunger and fill the syringe with the sample to be filtered. Pour the sample gently, trying to avoid transferring of the actived carbon to the syringe.

• Reinsert the plunger and filter the solution into the 100 mL beaker by pushing gently the syringe plunger.

The sample is now ready.

• Remove the cap and fill the Demineralizer Bottle with tap water.

• Replace the cap and shake gently for at least 2 minutes.

• If the solution is still turbid or colored, treat it again with a packet of active carbon. After use, throw the filter disc away and wash the syringe and the filter assembly well. Always use a new disc for another sample.

CONCENTRATED SAMPLES:

If the analysis result is over the method range, the sample should be diluted. The following procedure describe how to dilute the sample by a factor “N” (that is, to dilute by “N times”):

• Use the graduated cylinder to measure exactly V mL of sample. For volumes V < 20 mL, accurately dose the sample by mean of the syringe.

Note: To measure exactly 5 mL of sample with the syringe, push the plunger completely into the syringe and insert the tip into the sample. Pull the plunger out until the lower edge of the seal is on the 5 mL mark of the syringe.

• Open the upper part of the Demineralizer Bottle cap and gently squirt the demineralized water into the cylinder, up to the 100 mL mark.

Note: The ion exchange resin contained in the Demineralizer Bottle is provided with an indicator substance. The indicator will change from green to blue when the resin has been exhausted and needs to be replaced.

• Pour the solution in the large 170 mL beaker, replace the cap and invert several times to mix.

probable level of liquid

taken up by syringe

18 19

• If the solution contains some turbidity or color, add a powder packet of active carbon and follow the

procedure described in previous section Colored or Turbid Samples.

• Calculate the dilution factor N: N = 100/V Where: V is the volume of original sample poured in the cylinder, expressed in mL, and 100 is the final volume

in the cylinder, expressed in mL.

• When performing the reading, pay attention to multiply the read value by the dilution factor in order to obtain the real concentration of the analyte in the original sample:

Example: Reading = value A Dilution factor = N Real value in the original sample = A x N

Note: The methods Potassium Medium Range and Potassium High Range require a dilution of 1:5

(N = 5, V = 20 mL) and 1:10 (N = 10, V = 10 mL) of the sample. As the dilution is always done, it is already included in the final result and is not necessary to multiply by the dilution factor.

SAMPLE DILUTION

This meter is designed to determine low levels of hardness, typically found in water purification systems. When testing some other sources of water, it is not uncommon to come across levels of hardness that are

greater than the range of this meter. This problem can be overcome through dilution. Dilutions must be performed with hardness-free water or the

readings will be erroneous. A dilution to reduce the level of hardness by a factor of one hundred is performed as follows:

• Fill a 1 mL syringe with the sample.

• Place the syringe in a 50 mL beaker, making sure that the beaker is clean and empty, and inject 0.5 mL into the beaker.

• Fill the beaker up to the 50 mL mark with hardness-free water.

INTERFERENCES

Interference may be caused by excessive amounts of heavy metals.

• Press s or t to access the second level functions.
