7.5 Calibration and quantification

IC Net 2.0

129

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

, 1/y and 1/y

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

IC NET / Method / Calibration / Update

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

corresponding peaks obtained in the cur-

rent run.

Indexes Fill Index field for components with zero in-

dex.

Coefficients Recalculate all calibration coefficients for all

components (performs recalibration).
