f. For FID, NPD, TCD, ECD, and FPD, position the column so that the end of the
column extends the proper distance above the end of the ferrule as reported in
Table 14. For PDD see the instruction described at the

i. For FID, NPD, and TCD, insert the column into the detector, paying attention
to not force it further. Finger-tighten the retaining nut, then withdraw the
column 2-3 mm. Tighten the retaining nut an additional a quarter turn.
ii. For ECD and FPD, insert the notched septum on the column to hold the
retaining nut in this position. Thread the retaining nut into the detector but do
not tighten. Adjust the column position so that the septum contact the bottom
of the retaining nut. Finger-tighten the retaining nut until it starts to grip the
column plus a quarter turn.
iii. Remove the notched septum from the column.
g. For PDD the column must enter 136 mm into the pre-installed capillary column
adapter.
i. Make a mark on the column 136 mm from the end.
ii. Remove the knurled nut column inlet at the bottom of the detector. Slide the nut
overt the end of the column, followed by the appropriate column ferrule.
iii. Seat the ferrule in the detail of the column adapter and begin sliding the column
through the capillary column adapter and into the column inlet.
iv. Get the nut started on the threads and tighten it until you feel it contact the
ferrule, then back off half a turn.
v. Slide the column into the column inlet until the mark is flush with the surface of
the knurled nut, and secure the column in the adapter by tightening the knurled
nut finger tight only.
Note When inserting the capillary column into the PDD detector it might rarely
happen to feel a slight resistance. In this case, for proper column installation, pull
the column out slightly and adjust the angle before inserting it further.
