Note
Information regarding which guard column is suitable for your separa-
tion column can be found in the Metrohm IC Column Program
(which is available from your Metrohm agent), the leaflet provided
along with your separation column, the product information on the
separation column at
Chromatography), or obtained directly from your agent.
Caution
New guard columns are filled with solution and are sealed on both
sides with stoppers or caps, respectively. Before using the guard col-
umn, you need to ensure that this solution is miscible with the eluents
used (observe manufacturer's data).
Note
The guard column may only be installed after the initial start-up (see
Chapter 4.1, page 47) of the instrument. Until then, use the coupling
(6.2744.040) instead of the guard and separation column.
Note
Metrohm recommends, always to work with guard columns. These pro-
tect the separation column and can be exchanged regularly.
