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 t 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 "
!
".
