Conditioning cycles with CVS and CPVS
With CVS and CPVS the sweep is mainly in the positive voltage
area. Therefore, the default values are positive (compare to
Conditioning of solid state electrodes, section 3.4)
Start potential (V) [ -5...+5 V ; 0.2V ]
Start voltage for the cyclic conditioning sweep.
End potential (V) [ -5...+5 V ; 1.575 V ]
Final voltage for the cyclic conditioning sweep.
No. of cycles [ 0...X ; 0 ]
Number of conditioning cycles.
Initial electrode conditioning
Working with a RDE/SSE electrode, additional conditioning is nee-
ded (see Conditioning of solid state electrodes, section 3.4). With
CVS and CPVS initial "conditioning measurements" which include
Conditioning cycles, Pretreatment and Sweep should be done. It
should be conditioned until the determination value is stable.
Initial electrode conditioning
Check the checkbox to use conditioning.
No. of conditioning measurements [ 1...100 ; 1 ]
Number of replications of conditioning measu-
rements. The “total number of conditioning mea-
surements” is the No. of conditioning measure-
ments
multiplied with the number of Save last ..
sweeps
(Voltammetric tab). “Total number of con-
ditioning measurements” must not exceed 100.
or Auto Std.dev (%)[ >0.1 ; 1 ]
Define until which „Std.dev.“ the conditioning is
continued. The „Std.dev.“ is calculated from all sa-
ved sweeps of the last two replications of the
“conditioning measurement”.
Note: If you set a small value (e.g. < 1%), it can
take a long time until reaching the target.
Note: If both
No. of conditioning measurements [
1...100 ; 1 ] and Auto Std.dev (%) [ >0.1 ; 1 ] are
activated, the conditioning is finished as soon as
the first of the two criterias is reached.
