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.
No. of replications [ 1...10 ; 2 ]
Number of replications (= total number of measu-
rements) for each variation (sample, standard ad-
dition, calibration level, conditioning measure-
ment). For cyclic modes (CV, CVS, CPVS) the “total
number of measurements” is the
No. of replica-
tions multiplied with the number of Save last ..
sweeps ( Voltammetric tab). “Total number of mea-
surements” must not exceed 10.
Voltammetric tab with Calibration technique “LAT Record
intercept value”
The Voltammetric tab of the EDIT WORKING METHOD PARAME-
TERS window contains parameters for preparation procedures and
VA measurement modes. The parameters displayed depend on the
measurement mode selected in the
WORKING METHOD SPECIFICA-
TIONS window. With “LAT Record intercept value” following pa-
rameters have to be defined:
Initial mixing time (s) [ 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 (see Conditioning cycles with CVS and CPVS ,
section 6.3)
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 .
