Column Flushing

Automatic pump stop and/or column flushing after completion of analysis is settable.
By setting for column flushing, the flushing will be done automatically after the end of
analysis. When a salt solution has been used for analysis, for example, elution of the salt
component can be prevented by flushing the column with water.
An example is given where the column is flushed for 30 minutes with 100% liquid C 15
minutes after the end of analysis.
