3 Operating tutorial
This section introduces you to the operation of the 792 Basic IC by
means of a brief operating tutorial which describes the basic operat-
ing steps needed for the recording of an ion chromatogram using one
of the system files supplied.
The determination of the anionic content of a drinking water sample
with the METROSEP Anion Dual 1 column is used as an illustrative
example. Please note that the steps and parameter settings described
apply only to this example. If you use a different separating column
and system file, the procedures described in the tutorial must be
modified appropriately.
For further explanations of the operation, please refer to section 4.
