Changing the Air Inlet Filter

Changing the Air Inlet Filter

Objective
The following procedure is used to replace the air inlet filter. The installed air
pump uses ambient air (through this filter) to create pressure inside the
electrolyte bottle. The compressed air is needed to flush a capillary and to
inject a sample.
Frequency
Air filter replacement should be considered if the environment is very dusty
or if the system cannot generate enough pressure. We suggest that you change
the air filter at least every three months.

Accessing the Air Filter

The air filter is located inside the electrolyte and waste bottle compartment,
see
frequently.
If the instrument cannot build-up either pressure or a vacuum, check the
following:
• proper seal of the pressure bottle,
• proper seal of the vacuum bottle, and
• loose fittings on the bottles
If none of these reasons apply, call Agilent Technologies.
