Carrying out calibration

Preparing and starting calibration

When activated, the sample intake hose is backflushed with ultrapure water. The syringe
pump is flushed as well. The UV reactor and the TIC condensate container are emptied.
The analyzer shuts down. The UV light and the gas flow are turned off.
The control and analysis software provides the option to adjust the analysis to the indi-
vidual measuring task by selecting the method. An ideal measurement with its corre-
sponding method requires its own calibration for each analysis parameter and each
measuring channel. Not all parameters in a method need necessarily be calibrated.
Three calibration functions can be stored for each parameter in a method.
Carry out the calibration as follows:
} Select the sample feed type in the System state window:
[manual] or [Sampler].
ü The analyzer is initialized.
} Open the Measurement |Calibration menu option.
} In the query that follows, select either the method to calibrate or a preexisting cali-
bration table.
} Carry out the software instructions that follow.
ü The Calibration - Data of new calibration window opens.

} 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.
