In tiamo TM it is typically used as a single determination
in autorepeat mode. In other words, it is always ready
to do a titration as soon MagIC requires it. To set it into
autorepeat go to the Run window, right-mouse-click and
select
Properties Run window . Under Process select
Autorepeat determination . Close the window with .
 TitrIC pro III_pH calibration manual: Here the iAquatrode
is taken out of the titration vessel and placed into the
buffer solutions. Start this method only from tiamo
TM !
 TitrIC pro III_titer determination of HCl: This method is
used for the titer determination. It has to be used in
combination with the MagIC Net method
TitrIC pro
III_titer determination of HCl .
 TitrIC pro III_conductivity calibration: This method is
used for calibration of the conductivity sensor. It has to
be used in combination with the MagIC Net method
TitrIC pro III_calibration conductivity .
Import: Click on Method at the left (in MagIC Net and
tiamo TM ), then select under File / Method manager… / Edit /
Import… Import the methods related to TitrIC pro III with the
Dilution kit from the MagIC Net CD. You will find the
methods in the folder example/TitrIC of the CD
.
Note!
Alterations of these methods should only be carried out by a
person at the administrator level and who is thoroughly
familiar with tiamo
TM and MagIC Net
With the TitrIC pro – Combo Kit Dilution following analysis
can be carried out using the TitrIC pro III_dilution methods
in MagIC respectively tiamo
TM :
The whole procedure is controlled by the MagIC Net
software which is the master software. In tiamo
TM the
method TitrIC pro III is selected as a single determination.
Start the determination in autorepeat mode. To set it into
autorepeat go to the Run window, right-mouse-click and
select
Properties Run window . Under Process select
Autorepeat determination . Close the window with . Start
the determination. Now tiamo TM is waiting for the start
signal from MagIC Net via RS232.
In the MagIC Net software select the method TitrIC pro
III_dilution . Enter the required sample position, sample
identification etc. into MagIC Net. For value 1 choose
according to the list below:
 Value 1 = 1 complete analysis including titration and
ion chromatography.
 Value 1 = 2 only an ion chromatography analysis (e.g.
a calibration)
 Value 1 = 3 only a titration analysis
With Value 1 = 1 a complete analysis is carried out.
Depending on the entered dilution factor the following will be
done:
Dilution Factor = 1:
Depending on the measured conductivity an
appropriate dilution factor is automatically applied by
MagIC Net. The calculation factor is calculated
according to Time Program No. 2. The finally used
dilution factor is the integer of the conductivity divided
by 250.
Dilution Factor >1:
If a dilution factor is known it can be directly entered into the
sample table. It will be diluted accordingly. The conductivity
measurement has no influence on the dilution in this case.
E.g. With Value 1 = 2 an ion chromatographic analysis will
be carried out with the entered dilution factor. No dilution
factor will be calculated as no conductivity measurement will
take place.
