4.19 Connecting and rinsing the guard column
Guard columns protect separation columns and significantly increase their
service life. The guard columns available from Metrohm are either actual
guard columns or guard column cartridges used together with a cartridge
holder. The process of installing a guard column cartridge into the corre-
sponding holder is described in the cartridge leaflet.
NOTE
Metrohm recommends always working with guard columns. They pro-
tect the separation columns and can be replaced regularly as needed.
NOTE
Information regarding which guard column is suitable for your separa-
tion column can be found in the Metrohm Column Program (which
is available from your regional Metrohm representative), the column
leaflet and the product information at http://www.metrohm.com (Ion
Chromatography product area), or it can be obtained directly from your
representative.
CAUTION
New guard columns are filled with solution and sealed with stoppers or
caps on both sides.
Before inserting the guard column, ensure that this solution can be
mixed with the eluent being used (follow the information provided by
the manufacturer).
NOTE
Only connect the guard column after the initial start-up of the instru-
ment (see chapter 4.18, page 50). Until then, replace the guard column
and the separation column with couplings (6.2744.040).
