The parameters for the pretreatment can be set on this tab.
Stirring time
Waiting time after deactivation of the deaeration, during which the stirrer
is activated.
Input range
0.0 - 9,999.9 s (Increment: 0.1)
Default value
5.0 s
Potential 1
Potential that is applied to the electrodes during the Waiting time 1.
This potential can be used e.g. as cleaning potential for the electrochemi-
cal cleaning of solid-state electrode surfaces that have been contaminated
with products of electrode redox processes.
Input range
-5.000 - 5.000 V (Increment: 0.001)
Selection
off
Default value
off
Waiting time 1
Waiting time during which the Potential 1 potential is applied to the
electrodes.
Only editable for Potential 1
≠ off, otherwise inactive.
Input range
0.0 - 9,999.9 s (Increment: 0.1)
Default value
0.0 s
Potential 2
Potential that is applied to the electrodes during the Waiting time 2.
This potential can be used e.g. as deposition potential for the electro-
chemical preconcentration in Inverse Voltammetry.
Input range
-5.000 - 5.000 V (Increment: 0.001)
