5.12.2 Protection
To protect the separation column against foreign particles, which can
affect the separating efficiency, we recommend that both the eluent and
the samples undergo a microfiltration (filter 0.45 µm) before being aspira-
ted via the aspiration filter (6.2821.090).
We recommend always to use a guard column (see Chapter 3.16, page
46). This protects the separation column and considerably increases its
service life. Information regarding which guard column is suitable for your
separation 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
http://www.metrohm.com (product area Ion Chromatography)
or obtained directly from your agent.
The pulsation absorber (see Chapter 3.11, page 33) must be installed in
order to protect the column material from pressure concussion caused by
injection.
5.12.3 Storage
Always store the separation columns sealed and filled according to the
data of the column manufacturer when not using them.
5.12.4 Regeneration
Note
The regeneration is considered as the last measure, and not to be car-
ried out regularly.
If the separating properties of the column have deteriorated, the column
can be regenerated according to the specifications of the column manu-
facturer. In the case of separation columns available from Metrohm, the
specification for regeneration can be found on the leaflet provided along
with each column.
