from the

menu. The prepared table for the components fluo-
ride, chloride, nitrite, bromide, nitrate, phosphate and sulfate
is displayed below the chromatogram. For all peaks, which
could be allocated unambiguously to a component this table
contains the peak number in the
Peak
column and the reten-
tion time in the
Time
column. In the chromatogram itself, this
retention time is indicated by the cursor (vertical line).
If the
Peak
column contains a

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. This is done
by clicking on the chromatogram and moving the cursor with
the aid of the cursor keys <Í> and <Î> to the middle of
the peak and reading off the corresponding retention time in
