Number Row number (read-only).
Peak
Number of the peak in the chromatogram that cor-
responds to the given component. If this field con-
tains a
0, the peak number must be entered
manually.
Time
Expected retention time of the component in the
calibration run. After a new entry of the peak num-
ber the corresponding retention time is entered
automatically as soon as this field is clicked on
with the mouse.
Wind.% Identification window of the component. This
value is the maximum allowed difference of the ac-
tual retention time of the component and its ex-
pected retention time, measured as % of expected
retention time. The component will be identified
within its identification window only.
Ref. Reference component. The entry Yes defines
components as reference components; these en-
sure improved peak identification of the other
Ordi-
nary components
(details see on-line help).
Name Component’s name (cannot include spaces).
Rows with empty names are excluded from the ta-
ble of components when you leave the component
table editor.
Group Number of the group to which the components
are allocated. If group numbers ≥ 1 are entered
here then a group report can be outputted for
each group; this also contains the intermediate to-
tals for this group. This group report is produced
after the main report table.
Index Retention index for components with known in-
dex. In the case of an unknown index this value
should be equal to
0. For index calculation the
user must define index values for at least two
peaks, and all other values will be calculated by
the software using linear or logarithmic approxima-
tion (details see on-line help).
RF Response factor. This value corresponds to the
slope of the calibration curve (coefficient k
1
of the
calibration formula).
min C (max C) Minimum (Maximum) concentration value for
the component. Components whose concentration
leaves the range
min C…max C are marked in the
peak table by the sign "
! ".
