c Remove the previously installed spray chamber. Install the multimode
spray shield if not already installed.
d Orient the standard spray shield so the field-shaping electrode is at the
6 o'clock and 9 o’clock positions by loosening the two T10 screws that
secure the end plate, orienting the spray shield, and re-tightening the
two T10 screws (do not over-tighten).
e Install the multimode spray chamber on the spray chamber mount, close
the spray chamber, and fasten the latch. If needed, adjust the latch to
ensure that the O-ring seals completely. Use a ¼-inch × 5/16-inch wrench
to loosen the lock nut, adjust the latch to the proper fit, and then tighten
the lock nut so that the latch maintains its adjustment.
f Connect the multimode high voltage, APCI corona, and vaporizer heater
cables to the connector on the left side panel of the instrument.
g Connect the 1/8-inch nebulizing gas tubing from the LC/MS mainframe
to the nebulizer gas fitting.
h Connect the PEEK tubing from the selection valve (inside the front
cover) to the top of the nebulizer.
Surfaces can be extremely hot.
