6.3.2 Replacing the High Pressure In-line Filter

The high pressure in-line filter serves to remove particulate matter from the
mobile phase and is considered as a consumable item. If excessive pressure is
required to deliver the mobile phase (indicated on the pump display), it is
probable that the filter should be replaced.
To replace the high pressure in-line filter:
e) Remove the capillary (item 1, FIGURE 6-2) between the purge valve and the
filter unit.
