section.

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:

= ε

-log I/I
A = ε

c d

o

λ

or

c d

λ

Where:

-log I/I

=Absorbance (A)

o

I

=intensity of incident light beam

o

I =intensity of light beam after absorption

ε

=molar extinction coefficient at wavelength λ

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 83205 is based on special subminiature tungsten lamps and narrow-band
interference filters to guarantee both high performance and reliable results.

Four 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

or -I-.

o-

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 take place in 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.

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.

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)

• 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 of the cuvette is done by shaking the cuvette, moving the cuvette up and down. The

(c)(a) (b)

8 9

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

(c)(a) (b)

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

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.

METHOD REFERENCE TABLE

• 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.
