Unscrew the assembly tool (part number G2617-80540) into two pieces,
the ferrule guide and the compression fitting.
GRAPHPACK-3D ferrule
Slide the compression fitting onto the longer straight end of the new liner
with the threads pointing toward the end of the liner.
Place a GRAPHPACK-3D ferrule on the same end of the liner with the
recessed graphite end towards the compression fitting. Slide the ferrule on
so that about 2 mm of liner is exposed beyond the ferrule.
Slide the compression fitting up to meet the ferrule. Screw the ferrule
guide gently onto the compression fitting until it is finger tight.
Unscrew and remove the ferrule guide. Slide the compression fitting off
the other end of the liner. The ferrule should now be set with 1 mm of liner
exposed. Check that the graphite within the ferrule is flush with the top of
the metal collar.
Insert the glass liner into the inlet from above until the unpacked side of
the ferrule rests on the top of the inlet.
Replace the sampling head and reconnect the lines, if necessary.
