Cleaning procedure window
The CLEANING PROCEDURE window serves for electrochemical
cleaning of solid state electrodes at the 757 VA Computrace
Stand.
Cleaning solution [ XXX characters ; ]
Name of cleaning solution used for electrochemical clean-
ing of solid state electrodes.
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
Electrochemical regeneration of the solid state electrode by
a freely selectable number of conditioning 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 .
