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

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).

Retention time
Replace the expected retention times of the
components with the retention times of the cor-
responding peaks obtained in the current run.
