2.2 Glossary
Batch reprocessing
Batch reprocessing is understood to be the subsequent reproc-
essing of a series of chromatograms which have been loaded in
a batch reprocessing queue. During reprocessing with a selected
method the settings for calibration, integration, passport, ap-
pearance and report can be altered at will (for details, see section
10).
Calibration
Calibration is used to describe the method of determining the re-
lationship between the peak height or peak area found for one
component and its concentration in the sample. The result of the
calibration is a calibration function (calibration curve), which
shows the relationship between the amount of sample and the
evaluated quantity.
The determination of the calibration function with reference solu-
tions can be carried out as a one-point or as a multiple-point
calibration. The calibration method which is mainly used in ion
chromatography is the external standard calibration (absolute
calibration); calibration with an internal standard (relative cali-
bration) or tabulated calibration are also possible (for details,
see section 4).
Chromatogram
A chromatogram is a graphic plot of the elution curve (signal vs.
time) recorded following a chromatographic separation on a
separating column.
Chromatograms are stored as chromatogram files (
*.chw ) in the
Data directory. As well as the measuring data the chromatogram
files also contain the method parameters and system settings
which have been used for data recording, data processing and
remote control (for details, see section 8).
Determination
In order to carry out a determination a suitable system must be
selected for the separating problem. The result of the determina-
tion is a chromatogram, in which the measuring data and re-
sults of the determination are stored (for details, see section 8).
Device
The «IC Net» program supports remote control for Metrohm and
Bischoff instruments. Each instrument within a system is a de-
vice. Devices are stored as device files (
*.dev ) in the Devices di-
rectory. All Metrohm devices start with Me*.dev and all Bischoff
devices start with Bi*.dev (for details, see section 6).
Integration
Integration is to be understood as being the method for deter-
mining the peak area and peak height with the aid of approximate
