The interface of the Ion Analyser has been specially designed to clearly
guide you through every step of the programming and running of the
analyses, whether you are a supervisor or a routine user.
An important part of this interface is to check and control the presence of
different elements necessary to run the defined application.

1. Define your electrode(s)
Identify electrodes (including temperature sensors) to be used for the
analysis.
Electrodes can be created from the following lists, Catalogue, Other or
Copy from. When creating the electrode, define if electrode calibration is
required (or not), if yes specify the “periodicity” of the calibrations and the
standards to be used. Refer to chapter 3.

IMPORTANT
Before pressing the Run key, check the following points listed below:
1. Select the method by pressing 3 in the main window.
2. If a Question mark "?" is present in the electrode tab.
Programming error due to missing electrode parameters.
Contact your supervisor.
✶
3. Connect/Check electrode(s).
When installing/checking an electrode system, do not forget to
connect all the installed electrodes to the ION450 sockets and to
install these electrodes on the ION450 (Location = ION) or the
SAC80 or SAC90 Sample Changer (Location = SAC).
It is important to immerse, in the same measuring beaker, all the
installed electrodes having the same location.
For example: conductivity and pH measurements.
If your installed electrode system comprises either a conductivity
cell or a double platinum electrode with a combined pH electrode, the
electrodes must remain permanently immersed in the same beaker,
in order to measure the pH correctly. This is because it is the
conductivity cell (or the double platinum electrode) that provides the
connection to the ground and not the reference electrode.
This so-called " 3-electrode or differential measurement configuration
" will stop the conductivity cell altering the measurement at the pH
electrode.
When using this configuration for an electrode calibration, the
conductivity cell and the pH electrode must always be immersed in
the same beaker.
Important: Never remove an electrode or an electrode system
without running the Installation/checking procedure first. The
instrument needs to know its configuration at any time.
