18 Tighten the single compression bolt until you hear a click from the Intuvo
torque driver.
19 Loosely install the other compression bolt on the empty click and run bus
connector.
20 Pull the MS tail heater assembly a few millimeters towards the 9000 GC/MS
Tail until contact is made.
21 Close the MS tail heater assembly clamp, and hand tighten the thumb screw
to secure it.
22 Install the bus door on its hinges and close it.
23 Close the GC front door.
24 Install the spring and tip seal on the GC/MSD interface. Align, gently slide, and
screw the knurled tip seal retainer into the tip seal base. (See
“To Install the
GC/MSD Interface Tip Seal” on page 74.) The interface tip seal, spring, and
knurled tip seal retainer are not used with EI SS or Inert source.
25 Gently check the alignment of the ion source and the interface tip seal.
When the ion source is aligned correctly, the front analyzer chamber can be
closed all the way with no resistance except the spring tension from the
interface tip seal.
26 You can align the ion source and interface tip seal by wiggling the side plate
on its hinge. If the door still will not close, contact your Agilent Technologies
service representative.
27 Close the analyzer chamber. (See “To Close the Analyzer Chamber” on
page 220.)
CAUTION
Use the Intuvo torque driver to tighten the compression bolt until you hear one
click. Over-tightening can damage the flow path, strip the fittings, and cause
leaks.
CAUTION
Forcing the analyzer door closed if these parts are misaligned will damage the
tip seal or the interface or the ion source, or will keep the sideplate from
sealing.
