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 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).
