PRECISION AND ACCURACY

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 precision is expressed in the related measurement section as standard deviation at a specific concentration value of the analite. The standard deviation is obtained with a single instrument using a representative lot of reagents.

PRINCIPLE OF OPERATION

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/I o or

A = ε

λ c d

c d

Where:

-log I/I o

=Absorbance (A)

I o

=intensity of incident light beam

=intensity of light beam after absorption

=molar extinction coefficient at wavelength λ c =molar concentration of the substance d =optical path through the substance

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.

Instrument block diagram (optical layout)

A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed to 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 -I o-

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.

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 of 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 close the cuvette to prevent any contamination.

NEED TO KNOW

HI 83200 has a powerful interactive user support that assists the user during the analysis process.

Each step in the measurement process is help supported. A tutorial mode is available in the Setup Menu.

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, they should be removed by treatment with active carbon and filtration.

• 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 of 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.

(a) (b) (c)

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)

• 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;

(b)

(a) (b) (c)

USING CUVETTES

• Proper mixing of the cuvette is done by 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

9 shake vigorously

Pay attention to push the cuvette completely down in the holder.

• 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, or accuracy will be lost.

• 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 20°C (68°F). As a general rule of thumb, they should be doubled at 10°C (50°F) and halved at 30°C (86°F).

REAGENT BLANK CORRECTION

• Some methods require a “reagent blank correction”. The blank and the sample are prepared exactly in the same way, only the blank is deionized water instead of sample.

A blank cuvette may be used more than once: stability and storing conditions are described for each method in the related chapter.

INTERFERENCES

• In the method measurement section the most common interferences that may be present in an average wastewater 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.

• 1 Demineralizer Bottle with filter cap for about 12 liters of deionized water (depending on the hardness level of water to be treated)

SAMPLE PREPARATION PROCEDURE

Note: If the water sample to be analyzed is very turbid, let it stand in a beaker for a while until most of the solid particles have settled. Then, use the pipette to transfer the supernatant solution to the other beaker and prepare the samples as described below. To prevent the displacement of the settled solids at the bottom of the beaker, do not induce air bubbles into the solution.

IRRIGATION WATER (LR):

• Measure 100 mL of sample with the graduated cylinder.

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

• 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 100mL beaker by pushing gently the syringe plunger.

The sample is now ready.

Note: Filter at least 40 mL of solution if all the four methods will be tested. 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.

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.
