7.9 Inline Filter (Loading Pump)

7.9.1 Checking the Filter Frit for Permeability

Check the permeability of the frit in the inline filter at regular intervals.
1. Disconnect the capillary on the filter outlet.
2. Have the pump deliver water at a flow rate of 2 mL/min.
When the pump outlet is open, the pressure should be less than 0.5 MPa.
3. Replace the frit if necessary (→ page 209).
4. Reconnect the capillary to the outlet of the inline filter.
5. Test the loading pump for leakage (→ page 211).
Tip: As an alternative, you can check the permeability of the filter frit in the inline
filter also from Chromeleon by running the Mixer Frit Test (→ page 134).

7.9.2 Replacing the Inline Filter

Description
Inline filter (volume: 10 µL) with filter frit (porosity: 2 µm)
Capillary from purge unit to inline filter
1. Disconnect the capillaries on the filter inlet and outlet and remove the inline filter from
the pump.
2. Connect the capillaries to the replacement inline filter (observing the direction of flow
through the filter as indicated by an arrow on the filter) and place the filter below the
pump head in the pump enclosure.
3. In Chromeleon, verify that the StaticMixer property is set to InlineFilter_10µL. If
the property is not set to the correct value, the leak tests (→ page 134) may not
provide reliable results.
