7.5 Calibration and quantification
IC Net 2.2 171
Base Base for calculations ( Area or Height ) in
quantification and calibration procedures.
Indicates, which parameter is to be used as
a peak response.
Reference channel Channel which is used to measure area or
height (read-only).
Formula Formula for calibration function. There are
six possible calibration dependencies for
linear and nonlinear calibration curves.
Statistical weight Weighting parameter used to weight cali-
bration points deviations on calculating co-
efficients of the calibration formula. Apart
from the uniform weighting
1 the values 1/x ,
1/x 2 , 1/y and 1/y 2 are also possible.
Standard component Name of standard component in the case
of Internal standard calibration or Tabulated
calibration method (details see on-line help).
Concentration of standard
Concentration of standard component in
the case of
Internal standard calibration or
Tabulated calibration method (details see on-
line help).
7.5.8 Update calibration

Selection of this menu item opens the Update window.
Retention time Replace the expected retention times of the
components with the retention times of the cor-
responding peaks obtained in the current run.
Indexes Fill Index field for components with zero index.
Coefficients Recalculate all calibration coefficients for all
components (performs recalibration).
Coef. (balance) Recalculate coefficient of the universal com-
ponent. The aim of this action is to adjust the re-
sponse factor of this component so, that the total
