Inlet adapters
The GRAPHPACK-2M connector (the inlet adapter) at the bottom of the inlet is
sized to the column diameter. When a different diameter column is to be
installed, the adapter must be changed.
The adapter number is stamped on the side of the adapters. Select the smallest
hole diameter that will accept the column. See

Load the SERVICE method or reset the inlet and oven temperatures to
OFF or turn the main power switch off. Let the heated zones cool to room
temperature. Also, make sure that:
• If you have entered parameters that you do not want to lose, store
them as a method
• If the detector is on, turn it off.
Unscrew the column nut from the adapter. Remove the nut and the
column from the inlet.
With a 6-mm wrench, remove the inlet adapter, being careful not to lose
the silver seal inside. Save the adapter for later use.
