Procedure: Installing capillary columns in NPD and FID detectors
110
1. Assemble a brass nut and graphite/Vespel ferrule onto the adapter.
2. Insert the adapter straight into the detector base as far as possible. Hold the
adapter in this position and tighten the nut finger tight. Use a wrench to
tighten the nut an additional 1/4 turn.
3. Prepare the column (see page 101 for instructions). If the column id is greater
than 100 µm, follow steps 7 to 9. If the column id is less than 100 µm, follow
steps 4 to 6, then follow steps 8 and 9.
