Switching back to ESI operation
Before starting with the dismantling of the GC-
APPI interface turn off the mass spectrometer, the
APPI lamp (turn off the blue switch on APPI source
cover shown in figure 25, and unplug the power
cable), the source heating and the transfer line
heating (unplug both cables).
Wait until everything is cooled down!
When all parts are at room temperature, you can
uninstall the GC-APPI interface and re-connect the
ESI sprayer onto the mass spectrometer. Do not
forget to mount the sweep gas cone and to
change back to ESI from APCI in the instrument
configuration of the Orbitrap Fusion (see Figure 23
and 24).
