Installing capillary columns in the FPD
The FPD uses an adaptable fitting that can use both packed and capillary col-
umns. If your adaptable fitting does not have a capillary adapter installed,
begin with step 1. If the capillary adapter is already installed in your adaptable
fitting, begin with step 5.
Released: March 2004
Assemble the ferrules and a 1/8-inch brass nut on the column as shown.
See Table 13 for the proper ferrules. Trim off a short piece of column to
remove any ferrule fragments inside the column.
Insert the column into the detector until it bottoms. Do not attempt to
force it.
Slide the column nut and ferrule up the column to the detector and tighten
the nut finger tight.
Pull the column out 1 mm. Use a wrench to tighten the nut an additional
1/4 turn. The column should not move.
