Calibration points table
This table contains the basic information used to construct the
calibration curve:
Level Number of Calibration level .
Conc. Concentration of the current component in
the calibration sample. It is taken from the
concentration table.
Area (or Height) Peak height or area of the current compo-
nent, depending on calibration base.
File File name of calibration chromatogram that
stores data on the given calibration level.
Used Information whether the calibration level is
used for calibration curve calculation or not.
<Exclude point> Exclude the selected calibration point from
the list and recalculate calibration coeffi-
cients for the current component. Repeated
pressing includes the point again. You can
exclude points that drop out of the calibra-
tion curve watching for RSD values.
Component information
Component Allows to select the current component
from the list. It is possible also to scroll the
list of components by mouse, using the
special arrow buttons on the right.
Retention time Retention time of the selected component
(read-only).
Concentration Concentration of the selected component
(read-only).
Calibration parameters
Calibration method Method used for calibration procedure:
External standard calibration
Absolute calibration. It is the basic calibra-
tion procedure in ion chromatography.
Internal standard calibration
Relative calibration.
Tabulated calibration
Relative response factor calibration (sim-
plified method of external standard calibra-
tion).
Local If this checkbox is marked then the corre-
sponding parameter is valid for the current
component only. Otherwise this parameter
is global (i.e. default for all other compo-
nents).
