C a u t i o n
Applying more than 5 psi pressure to the Electrospray chamber will cause
a relief valve to open. If the relief valve opens, remove all pressure from
the Electrospray chamber and the relief valve will reset automatically.
3.
With a sample solution installed in the bottom half of the
pressure chamber, apply up to 5 psi pressure to the aerosol exit
for 15 seconds.
4.
Remove pressure from the aerosol exit and run the Electrospray
under normal operating conditions to check if the capillary is
unplugged. If not, repeat steps 1–4 except apply back pressure
for several minutes until bubbles can be seen exiting the
capillary into the sample vial. If bubbles are not seen after
5 minutes at 5 psi back pressure, refer to the alternative
solutions mentioned earlier in this chapter to unplug the
capillary.
