PRINCIPLE OF OPERATIONPRINCIPLE OF OPERATION

PRINCIPLE OF OPERATION

PRINCIPLE OF OPERATIONPRINCIPLE 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 physicochemical characteristics of substance according to the Lambert-Beer Law:

-log I/Io = ελ c d

A = ε

c d

Where:

-log I/Io=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

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 Hanna's C 99 & C 200 multiparameter photometers is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

Four measuring channels (at four different wavelengths) allow a wide range of tests.

C 200 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 cuvet. The optical path is fixed by the diameter of the cuvet. 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.

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

The cuvet 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) cuvets are optically identical to provide the same measurement conditions. Whenever possible use the same cuvet for both.

It is also necessary that the surface of the cuvet is 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 cuvet walls with hands.

Furthermore, in order to maintain the same conditions during the zeroing and the measuring phases, it is necessary to close the cuvet to prevent any contamination.

A zero reading was not taken. Follow the instruction described in the measurement procedures for zeroing the meter.

Under range. A blinking "0.00" indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure that you use the same cuvet for reference (zero) and measurement.

1) A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and rerun the test.

2) A flashing value lower than the maximum concentration indicates a low signal-to-noise ratio condition. In this case accuracy of the result is not guaranteed. Repeat the reading procedure.

TIPS FOR AN ACCURATE MEASUREMENTTIPS FOR AN ACCURATE MEASUREMENT

TIPS FOR AN ACCURATE MEASUREMENT

TIPS FOR AN ACCURATE MEASUREMENTTIPS FOR AN ACCURATE MEASUREMENT

The instructions listed below should be carefully followed during testing to ensure best accuracy.

• Color or suspended matter in large amounts may cause interference, therefore, these should be removed by treatment with active carbon and by prior filtration.

• For a correct filling of the cuvet: the liquid in the cuvet forms a convexity on the top; the bottom of this convexity must be at the same level of the 10 mL mark.

• In order to measure exactly e.g. 0.5 mL of sample or reagent with the 1 mL syringe, push the plunger completely into the syringe and insert the tip into the solution. Pull the plunger up to above the 0.0 mL mark. Take out the syringe and clean the outside of the syringe tip. Then, adjust the plunger to the 0.0 mL mark (the lower edge of the seal must be exactly on the 0.0 mL mark). 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 cuvet, push the plunger down 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 cuvet, even if the tip still contains some reagent or sample.

10 mL

• Proper use of the dropper: to get good reproducible results, tap the dropper on the table for several times and wipe the outside of the dropper tip with a cloth. Always keep the dropper bottle in a vertical position while dosing the reagent.

• 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.

(a)

(b)

(c)

• It is important that the sample does not contain any debris. This would corrupt the readings.

• Do not let the reacted sample stand too long after reagent is added, or accuracy will be lost.

• In order to avoid reagent leaking and to obtain more accurate measurements, it is recommended to close the cuvet first with the supplied HDPE plastic stopper and then with the black cap.

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

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

• 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 cuvet for zeroing and measurement.

• It is important to discard the sample immediately after the reading is taken because the glass might become permanently stained.

• All the reaction times reported in this manual are referred to 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).

Note: For better accuracy wash glassware with HCl 6N.

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.

Now, follow normal measurement procedure. The true value of the sample is the reading obtained multiplied by a factor of one hundred (the dilution factor).

The conversion factors to convert readings in mg/L to French degrees (FD), German degrees (DD) and English degrees (ED) of hardness are as follows:

1 mg/L = 0.1 FD = 0.0556 DD = 0.07 ED.
