⇒ Click on or select Calibration / Components from the
Method menu. The prepared table for the components fluo-
ride, chloride, nitrate, and sulfate is displayed below the
chromatogram. For all peaks which could be allocated un-
ambiguously to a component this table contains the peak
number in the Peak column and the retention time in the Time
column. In the chromatogram itself this retention time is indi-
cated by the cursor (vertical line).
⇒ If the Peak column contains a 0 the peak must be manually
allocated to a component. In this case, insert the peak num-
ber from the chromatogram into the Peak column and click
the Time field on this row with the mouse. The corresponding
retention time is then inserted automatically as the new time
for this component.
⇒ For each correctly allocated peak click on the retention time
in the Time column. This time is automatically shown in the
chromatogram by the cursor. If the retention time is not lo-
cated in the area of the middle of the peak then the value in
the Time column should be adapted accordingly.
