6.2.5 Solutions
The solutions to be used must, as usual, be defined in tiamo
TM
. Connect the Dosino of the 50 mL
Dosing unit to MSB 1 of the 905, the Dosino of the 10 mL Dosing unit to MSB 2 and the Dosino of the
20 mL Dosing unit to MSB 3. The user is automatically requested to save the solutions – click on
.
In order to ensure compatibility with the methods provided, they must be named as described below.
ƒ At the left click on
Configuration , then at the top right under Titrants/Solutions double-click on the
appropriate (empty) entries and enter the following under Solution name and Concentration :
Configuration table for titrants/solutions
Now the tubing lengths and ports are defined for each Dosing unit under Edit/Properties…/ Dosing unit as
follows:
Anion Cation HCl
Port Length Port Length Port Length

6.2.6 Electrodes
ƒ pH electrode: Under
Configuration/Sensors click on Edit/New/pH electrode and enter under Sensor
name Aquatrode Plus , type in the desired sensor information (e.g. serial number) and click on
.
ƒ Conductivity sensor: Under
Configuration/Sensors click on Edit/New/other sensor and enter under
Sensor name Conductivity sensor type in the desired sensor information and click on .
6.2.7 Methods
The following seven methods are provided:
ƒ
TitrIC 6 - complete run: With this method all the available parameters are measured and the IC
measurement is initiated.
ƒ
TitrIC 6 - preparation of titration equipment: This method is used for preparing all titration instruments,
i.e., rinsing the tubing connections of the Dosing Units with reagents or deionized water and
rinsing the external cell. Start this method only from tiamo
TM
– not from TitrIC!
ƒ
TitrIC 6 - IC calibration - anion & cation: This method is used for calibrating the IC measurements
with standard solutions without the titration part of a typical TitrIC measurement; this means that
a lot of standard solution can be saved.
ƒ
TitrIC 6 – manual pH calibration: Here the Aquatrode is taken out of the titration vessel and placed
into the buffer solutions. Start this method only from tiamo
TM
!
ƒ
TitrIC 6 – semi automated pH calibration: With this method the pH electrode is calibrated
automatically; the buffer solutions are flushed into the titration vessel. Start this method only
from tiamo
TM
– not from TitrIC!
