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.
