Base Base for calculations ( Area or Height ) in quantifi-
cation and calibration procedures. Indicates,
which parameter is to be used as a peak re-
sponse.
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 calibration
points deviations on calculating coefficients 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 the standard component in the case
of Internal standard calibration or Tabulated calibra-
tion
method (details see on-line help).
Concentration of standard
Concentration of the standard component in
the case of Internal standard calibration or Tabu-
lated calibration method (details see on-line
help).

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 re-calibration).
Coef. (balance) Recalculate coefficient of the universal compo-
nent. The aim of this action is to adjust the re-
