Detailed Charger Column Cleaning Procedure
Note: This procedure is easier to perform on a surface that is
approximately waist high. Most of the steps in this procedure can be
done by one person, but several steps may require assistance.

High voltage is accessible in several locations within this instrument.
Make sure you unplug the power source to the instrument before
performing maintenance procedures. Use appropriate ESD precautions.
To perform the detailed charger column cleaning procedure, proceed as
follows:
1. Power off the equipment and wait 5 minutes for the internal capacitors
to discharge.
2. Remove the top cover and both side panels of the EEPS spectrometer.
(Refer to Figure 6-1 and the previous cleaning procedures if necessary.)
3. Open the front panel (there are 3 screws on the inside left). Prop the
door open using a binder clip or clamp.
4. Remove the sample inlet tube from the top of the charger column
(Figure 6-2 above).
5. Remove the charger sheath flow tube from the charger column
(Figure 6-14). You must push the retaining ring evenly into the
connector before pulling the hose free. If you try to simply pull on
the hose, it will become harder to remove.
