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).

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.
