Plating solution [ 48 characters ; ]

Name of electrolyte solution used for film deposition.

Stirrer/RDE (rpm)

[ 0...3000 rpm ; 2000 rpm ]

Revolutions per minute of the rotating disk electrode. The
stirring of the RDE remains active during all preparation pro-
cedure steps until the start of the cleaning sweep.

Purge time (s)

[ 0...80600 s ; 300 s ]

Time of inert gas purging before the first measurement of the
sample solution.

Conditioning

cycles

Before deposition, the solid state electrode can be electro-
chemically regenerated by a freely selectable number of con-
ditioning cycles. For every cycle, the voltage is changed at a
sweep rate of 1 V/s to the

End potential

and then decreased

at the same rate back to the

Start potential

.

Start potential (V)

[ -5...+5 V ; -1.2 V ]

Start voltage for the cyclic conditioning sweep.

End potential (V)

[ -5...+5 V ; -0.1 V ]

Final voltage for the cyclic conditioning sweep.

No. of cycles

[ 0...X ; 0 ]

Number of conditioning cycles.

Deposition potential (V)

[ -5...+5 V ; -0.8 V ]

Voltage applied to the electrodes during the

Deposition time

.

Deposition time (s)

[ 0...80600 s ; 10 s ]

Time during which the

Deposition

potential

is applied to the

electrodes.

Cleaning potential (V)

[ -5...+5 V ; -0.05 V ]

Voltage applied to the electrodes during the

Cleaning time

.

Cleaning time (s)

[ 0...80600 s ; 10 s ]

Time during which the

Cleaning

potential

is applied to the

electrodes.
