Separation column
The intelligent separation column (iColumn) is the heart of the ion chro-
matographic analysis. It separates the different components correspond-
ing to their interactions with the column. Metrohm separation columns
are equipped with a chip on which their technical specifications and their
history (first use / setting up, operating hours, injections, …) are saved.
Note
Information regarding which separation column is suitable for your
application can be found in the Metrohm IC Column Program, the
in the product area ion chromatography, or
obtained directly from your agent.
Caution
New separation columns are filled with solution and are sealed on both
sides with stoppers. Before using the column, you need to ensure that
this solution is miscible with the eluents used (observe manufacturer's
data).
You can find the separation columns and guard columns currently availa-
ble from Metrohm in the Metrohm IC Column Program, or in the Internet
test chromatogram and an leaflet are provided along with each column.
You can request detailed information on special IC applications in the cor-
responding "Application Bulletins" or "Application Notes", available
