Commissioning,
measuring, calibration
Commissioning The combination electrodes except the Micro are delivered with an
irrigation cap. The irrigation cap can also be used as storage equipment
between measurements. Due to its small pipe diameter, the micro
model is stored in a screw-top glass pipe. The electrodes are filled with
reference electrolyte solution in the factory. Prepare the combination
electrode for measuring as follows:
•
The closure of the refilling opening consists of a slide. Open the refilling
opening for the reference electrolyte solution.
The refilling opening must always be open during calibration and
measurement!
Refilling
opening
•
The bridge electrolyte (3 mol/1 KCI) that fills the item during delivery can be
replaced as needed with an electrolyte solution that matches the sample. For
a stabile measurement, the conductivity of the individual bridge electrolyte
should be at least 10 mS/cm.
•
The colored, iodine electrolyte solutions of the IoLine electrodes are inside a
closed system and must therefore not be refilled. You m ust make sure that
the bridge electrolyte is free of silver ions.
Note
The bridge electrolyte must be free of silver ions.
•
Connect the combination electrode to the meter
•
Calibrate the combination electrode according to the operating manual of the
meter. When doing so, observe the general rules on the following page.
•
Make sure the refilling opening for the reference electrolyte solution is open.
•
Avoid the displacement of any solution (sample or buffer solution) from one
measurement to the next by taking the following measures:
- Shortly rinse the calibration and sample beakers with the solution the
beakers are to be filled with next.
- Between measurements, rinse the combination electrode with the solution
that follows. Alternatively, you can also rinse the combination electrode with
deionized water and then carefully dab it dry.

Storage
•
Immerse the combination electrode in the solution in a vertical or slightly tilted
position.
•
Make sure the immersion depth is correct. The junction must be completely
submersed in the solution. At the same time, the level of the reference
electrolyte must be at least 2 cm above the level of the solution.
•
Provide approximately the same stirring conditions for measuring as for
calibrating.
The frequency of subsequent calibrations depends on the application. Many
meters provide an option where you can enter a calibration interval. After the
calibration interval has expired, the meter will
automatically
remind you of the due
calibration.
Storage
With the refilling opening open, immerse the combination electrode in
in reference electrolyte (KCl 3 mol/L, Ag+ free). Observe the minimum depth
of immersion. Prior to the next measurement, shortly rinse the combination
electrode with the test sample or deionized water.
Note
Prevent contact of the pH membrane to the beaker bottom to avoid scratches
on the pH membrane.
Put the clean combination electrode in the watering cap that is filled with
reference electrolyte (KCl 3 mol/L, Ag

Note
pH combination electrodes must not be stored dry or in deionized water. The
combination electrode could be permanently damaged by this. If the liquid in
the irrigation cap has dried up, condition the combination electrode in

Note
During longer storing periods, salt sediments may develop on the watering
cap. They do not affect the measuring characteristics and can easily be removed with deionized water when the combination electrode is put into operation again.

Aging, Maintenance and cleaning
IoLine
Aging
Every pH
With aging, the responding behavior becomes slower and the electrode slope
and asymmetry change. Moreover, extreme operating conditions can
considerably shorten the lifetime of the combination electrode. These are:
•
Strong acids or lyes, hydrofluoric acid, organic solvents, oils, fats, bro- mides,
sulfides, iodides, proteins
•
High temperatures
•
High changes in pH and temperatures
•

Maintenance
During operation, a small amount of reference electrolyte leaks through the
junction from the
If the level of reference electrolyte becomes too low with time, refill it through
the refilling opening. Refilling is very easy with the enclosed dropping bottle.
Proceed as follows:
•
Cut off the tip of the dropping bottle at a right angle until the opening in the tip
can be seen
•
Open the refilling opening of the combination electrode
•
Press the tip of the dropping bottle into the refilling opening while turning it
slightly
•
Pump the reference electrolyte in the shaft using the dropping bottle
