2 Installing GC Columns
5 Slide the column into the GC/MSD interface (Figure 9) until you can pull it
out through the analyzer chamber.
6 Break 1 cm off the end of the column (page 34). Do not let any column
fragments fall into the analyzer chamber. They could damage the high
vacuum pump.
7 Clean the outside of the free end of the column with a lint-free cloth
moistened with methanol.
8 Adjust the column so it projects 1 to 2 mm past the end of the interface.
Use the flashlight and hand lens if necessary to see the end of the column
inside the analyzer chamber. Do not use your finger to feel for the column
end.
