(Voltammetric tab). “Total number of
measurements” must not exceed 10.
Voltammetric tab with Calibration technique “DT Record
calibration curve”
The Voltammetric tab of the EDIT WORKING METHOD PARAME-
TERS
window contains parameters for preparation procedures and
VA measurement modes. With the Calibration technique "DT Re-
cord calibration curve" the Voltammetric parameters are not edit-
able. They depend on the parameters defined for recording the
calibration curve.
Following parameters have to be defined:
Initial mixing time (s) [ read only ] [ 0...80600 s ; 10 s ](see Initial
mixing time with CVS and CPVS, section 6.3)
Time of mixing before the first measurement of
the sample solution.
Conditioning Cycles [ read only ] (see Conditioning cycles with CVS
and CPVS, section 6.3)
Start potential (V) [ -5...+5 V ; 0.2 V ] [ read only ]
Start voltage for the cyclic conditioning sweep.
End potential (V) [ -5...+5 V ; 1.625 V ] [ read only ]
Final voltage for the cyclic conditioning sweep.
No. of cycles [ 0...X ; 0 ] [ read only ]
Number of conditioning cycles.
Pretreatment (see Pretreatment with CVS and CPVS, section 6.3)
Cleaning potential (V) [ -5...+5 V ; 1.625 V ] [ read only ]
Voltage applied to the electrodes during the
Cleaning time.
Cleaning time (s) [ 0...80600 s ; 0 s ] [ read only ]
Time during which the Cleaning potential is app-
lied to the electrodes.
Equilibration potential (V) [ -5...+5 V ; 1.625 V ] (This pa-
rameter is with CPVS part of the sweep)
Voltage applied to the electrodes during the
Equilibration time.
Equilibration time (s) [ 0...80600 s ; 5 s ] (This parameter is
with CPVS part of the sweep)
Waiting time before starting the sweep; with Equi-
libration potential
applied to the electrodes. If the
checkbox
Hydrodynamic (measurement) is not che-
cked, the stirrer is switched off during that time.
Sweep [ read only ]
The sweep parameters depend on the mode (see
CVS - Cyclic Voltammetric Stripping section 3.2,
