Start potential (V) [ -5...+5 V ; 0.2 V ]
Start voltage for the cyclic conditioning sweep.
End potential (V) [ -5...+5 V ; 1.625 V ]
Final voltage for the cyclic conditioning sweep.
No. of cycles [ 0...X ; 0 ]
Number of conditioning cycles.
Pretreatment
(see
Pretreatment with CVS and CPVS
, section 6.3)
Cleaning potential (V) [ -5...+5 V ; 1.625 V ]
Voltage applied to the electrodes during the
Cleaning time
.
Cleaning time (s) [ 0...80600 s ; 0 s ]
Time during which the
Cleaning potential
is ap-
plied 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
Equilibration potential
applied to the electrodes. If
the checkbox
Hydrodynamic (measurement)
is not
checked, the stirrer is switched off during that
time.
Sweep
The sweep parameters depend on the mode (see
CVS - Cyclic Voltammetric Stripping
section 3.2,
and
CPVS - Cyclic Pulse Voltammetric Stripping
section 3.2)
Substances tab with Calibration
technique “MLAT”
The
Substances
tab of the
EDIT WORKING METHOD PARAMETERS
window contains parameters for the definition and recognition of
substances, for the definition of standard solutions, for peak eva-
luation and results calculation. The parameters displayed depend
on the
Calibration
technique selected in the
WORKING METHOD
SPECIFICATIONS
window. With “MLAT Standard addition for brigh-
teners” following parameters have to be defined:
Substance [ 24 characters ; ]
Substance name. For the assignment of a found
peak to this substance the checkbox on the left
side of the substance name must be checked.
With CVS:
Peak pos. +/- (V) [ -5...+5 V ; 0 V ]
Position of the peak voltage for the substance and
tolerance for this verification voltage.
