Function Electrochemical regeneration of carbon electrodes.

Parameter Range; Default value / Meaning

U.start -3000...3000 mV; -1200 mV

Initial voltage of conditioning cycles

Initial voltage for every conditioning cycle.

U.end -3000...3000 mV; -100 mV

Final voltage of conditioning cycles

Final voltage for every conditioning cycle.

Cycles 1...60000; 10

Number of conditioning cycles

This parameter defines the frequency of conditioning of the electrode.

Rate 1 1...10000 mV/s; 1000 mV/s

Rate from U.start to U.end

Sweep rate for the conditioning cycles form U.start to U.end.

Rate 2 5...50000 mV/s; 10000 mV/s

Rate from U.end to U.start

Sweep rate for the conditioning cycles form U.end to U.start.

Description The CONDC instruction starts a freely selectable number of conditioning

cycles for the electrochemical regeneration of carbon electrodes (e.g.

glassy carbon).

Comments Before the call-up of CONDC, the RDE electrode must be selected. While

is possible to run CONDC with other electrode types, this is not realistic.
