Intuvo 9000 GC Column Maintenance 3
5977B Series MSD Operating Manual 73
16 Screw the 9000 GC/MS Tail column nut to the transfer line threaded
connector finger tight, then use a ¼-inch wrench to tighten the nut an
additional 20 to 30 degrees.
17 Loosely install the two compression bolts.
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 tip seal and spring on the GC/MS interface. Align, gently slide,
and screw the tip seal into the tip seal holder. (See “To Install the Interface
Tip Seal” on page 76.)
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 196.)
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.
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.
