2. Rotate the ion source housing locking levers 90 degrees to lock the ion source housing
onto the ion source mount assembly.
3. Reinstall the ion source housing drain tube:
a. Connect the 1 in. ID Tygon™ tubing (P/N 00301-22922) to the ion source housing
drain fitting.
b. Attach the free end of the hose to a dedicated drain system. Vent the drain system to
a fume exhaust system.

CAUTION Prevent solvent waste from backing up into the ion source and mass
spectrometer. Always ensure that liquid in the drain tube is able to drain to a waste
container.
CAUTION Do not vent the ion source drain tube (or any vent tubing connected to the
waste container) to the same fume exhaust system to which you have connected the
forepump. The ion source chamber and analyzer optics can become contaminated
with mechanical pump oil if the ion source drain tube and the (blue) forepump
exhaust tubing are connected to the same fume exhaust system.
Your laboratory must be equipped with at least two fume exhaust systems. Route the
(blue) forepump exhaust tubing to a dedicated fume exhaust system. Route the drain
tube from the ion source to a waste container. Vent the waste container to a dedicated
fume exhaust system.
