technique “DT Suppressors with
calibration curve”
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 “DT Suppressors with calibration
curve” 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.
With CPVS:
Step potential [ read only ; step 1: 0.2 V ]
Displays the potential values, which are defined in
the window

button to open
the

window for the selected substance.
Plating bath solution
Definition of plating bath solutions for standard
addition. The concentration of the plating bath is
not known (this is the concentration to be deter-
mined).
No. [ 0...8 ; 0 ]
Number of addition solution used for manual or
automatic addition. For automatic additions, this
number is also the Dosing Device number. Nor-
mally, only one plating bath solution is needed
(the one which is analyzed).
Achtung: Dosino 1..3 refer to Dosinos connected
to the 797 VA Computrace. Dosino 4...7 refer to
Dosinos connected to the 846 Dosing Interface (to
MSB 1...4).
Volume (mL) [ > 0.01 mL / var ; 0 mL ]
Addition volume. For entering variable addition
volumes, click the
button to open the
EDIT
VARIED ADDITION
window for the selected sub-
stance (details see
Variable addition
, section 5.2).
In this case,
