Operating the Electrospray 4–9
!
C a u t i o n
Buffer should be run before shutting down the Electrospray to clean the
capillary. Subsequently, the Electrospray should be run without a sample
to allow the air to clear the capillary of liquid. Follow the procedure in this
section to prolong capillary life and to avoid deposits on the inside of the
capillary.
1. Purge the capillary (see section, “ Purging the Capillary ” in
Chapter 5, “Maintenance”).
2. Remove the bottom half of the pressure chamber.
3. Close the lid of the vial and remove it.
4. Replace the bottom half of the pressure chamber without
inserting a vial to clear the liquid from the capillary and run air
through it.
5. View the capillary through the viewing window to determine
when the liquid has been cleared from the capillary. This
process takes approximately 5 minutes with a standard buffer
solution.
6. Turn the pressure regulator knob until the pressure gauge
reads zero psi.
7. Turn the air and CO
2
rotameters to read zero L/min.
8. Turn the voltage knob counterclockwise until it reaches its
stopped position.
9. Turn the power switch off.
