To Switch from the CI Source to an EI XTR, SS, or Inert Source
Procedure
1 From the Tune and Vacuum Control view, vent the MSD. (See “To Vent the
MSD” on page 113.) The software will prompt you for the appropriate
actions.
2 Open the analyzer. (See “To Open the Analyzer Chamber” on page 152.)
3 Remove interface tip seal and spring if switching to an EI SS or EI Inert
source.
4 Install the EI source. (See “To Install the EI XTR, SS, or Inert Source” on
page 193.)
5 If installing an EI XTR source, locate the brown extractor wire from storage
and connect it to the extractor lens and the source board.
6 Place the CI source in the ion source storage box.
7 If installing an EI SS or Inert source, remove the interface tip seal and
spring and put it in the CI storage container.
8 Pumpdown the MSD. (See “To Pumpdown the MSD” on page 116.)
Always wear clean gloves while touching the analyzer or any other parts that go inside
the analyzer chamber.
Electrostatic discharges to analyzer components are conducted to the side board
where they can damage sensitive components. Wear a grounded antistatic wrist strap,
and take other antistatic precautions before you open the analyzer chamber.
(See “Electrostatic discharge” on page 148.)
