The smart separation column (iColumn) is the heart of ion chromato-
graphic analysis. It separates the different components according to their
interactions with the column. Metrohm separation columns are equipped
with a chip where their technical specifications and history (start-up, oper-
ating hours, injections etc) are stored.
NOTE
Information regarding which separation column is suitable for your
application can be found in the Metrohm Column Program, the
product information for the separation column or it can be obtained
through your representative.
