To Install the Interface Tip Seal
Materials needed
• Interface tip seal (G3870-20542)
The interface tip seal must be in place for the EI XTR source and HES.
Procedure
1 Verify that the EI XTR source or HES is installed. This tip seal and its spring
must not be installed when an EI SS or Inert source is installed.
2 Place the tip seal spring over the end of the interface.
3 Remove the interface tip seal from the ion source storage box, and place it
over the end of the interface.
4 Gently check the alignment of the analyzer and the interface.
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.
