2 Installing 8890 GC Columns
To Install a Capillary Column in the GC/MSD Interface Using the Self-Tightening Column Nut
5977B Series MSD Operating Manual 45
11 Hand-tighten the nut. (See Figure 7.) Ensure the position of the column does
not change as you tighten the nut. Do not over tighten the nut.
12 Tighten the nut in the clockwise direction. Continue to tighten until you feel
the ferrule grip the column.
13 Check the GC oven to ensure that the column does not touch the oven walls.

14 Install the spring, tip seal, and knurled tip seal retainer on the GC/MSD
interface. (See“To Install the GC/MSD Interface Tip Seal” on page 50.) Do
not use the tip seal, spring, and knurled tip seal retainer with an EI SS or Inert
source. The interface socket on these sources does not allow the tip seal
installation to fit. (See Figure 64 on page 199.)
Use care when placing the tip seal on the GC/MSD interface to avoid
damaging the column.
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.
