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.
– Enter selection field:
Enter the content of the preparation water as a value.
Specify the normalized preparation water blank value 1 ml. If the preparation wa-
ter blank value is not taken into account, a
"0"
is entered in the input field.
}
Complete the calibration table for each parameter in accordance with the standard
solutions provided.
}
In the Rep. column, the software automatically accepts the number of repeat mea-
surements set in the method. If outlier selection is enabled in the method, the maxi-
mum number of repeat measurements is entered.
If necessary, change the number of repeat measurements for each standard solution
manually.

If the calibration table is to be used again later: Save the calibration table with the
CalibrationTable |Save CalibrationTable or Save CalibrationTable as menu option.
Calibration tables are automatically assigned the *.kaltab file extension and are
stored under ...\Calibration\Tables.
