Select the calibration type in the Calibration Parameters group:
– Preferably, perform Multiple point calibrations with a
constant sample volume
and variable concentrations. The volume set in the method is entered automati-
cally in the constant sample volume input field. Only change the presets if the in-
jection volume of the standard solutions differs from the volume set in the
method.
}
For calibrations with a
constant concentration
, enter the concentration of the stan-
dard solution in the input field.
}
Enter the number of calibration points in the Number of standards input field.
}
Select the analysis parameters of the loaded method to calibrate in the Analysis pa-
rameters field.
– Activate the IC and TC parameters individually for calibration of the NPOC plus
parameter and higher concentrations of c > 0.5 mg/l.
}
Use the calibration for the TOC/NPOC parameter for the lower concentration range.
A single point calibration is sufficient in the lower concentration range.

The software displays the sample feed type under Sample introduction. The indica-
tion is for information only and cannot be modified.

Select how to take the blank value of the prepared water of the standard solutions
into account in the Preparation blank group
– Measure selection field:
The content of the preparation water is measured separately immediately before
calibration. To do this, place a vessel with preparation water at the first position
on the autosampler.
With manual sample supply, the software sends a prompt to provide the prepara-
tion water.
