Capillary Column Installation; Cutting Capillary Columns - ABB PGC2000 Operation And Service Manual

7. Allow zone temperatures to stabilize.
8. Check and adjust carrier and makeup gases flow rates.
9. Ignite FID (if applicable).

Capillary Column Installation

1. Inspect the ends of the column. The ends should be round and burr free. If either column end is
not round or burr free, the column end must be trimmed as described in "Cutting Capillary
Columns."
2. Insert the end of the column through the back of the tubing nut.
3. Insert the column end through the new ferrule.
4. Slide the ferrule down the length of the column approximately three inches.
5. Insert the extended column length and the end of the ferrule into the appropriate tubing
connection at the sample valve.
6. Connect the tubing nut and finger-tighten; then tighten it an additional 1/4-turn with an open-end
wrench.
7. Test the column for a secure connection by gently pulling the column at the 1/8-inch tubing nut.
Any withdraw should be corrected. Continue to tighten the nut until the column is securely
connected at the fitting.
8. Repeat steps 1 through 7 for the other end of the column.
9. For columns connected to an FID, insert the column end into the FID analysis inlet connection
until it stops against the jet. Then withdraw the column approximately 1/16-inch and tighten the
nut finger tight. Tighten the nut an additional 1/4-turn with an open-end wrench, then check it for
a secure fit.
If a metal capillary column is used, particular care should be taken to ensure that
the column does not contact the jet. The metal column will conduct electricity and
could cause an electrical short at the jet.
10. Apply carrier gas and check for leaks. Further tighten the two fittings as required to stop any
leaks.
11. Install all analyzer covers and doors.
12. Perform the analyzer startup procedure as described in Section 2.

Cutting Capillary Columns

The procedure for cutting glass or metal capillary columns is the same, except that a small sharp file
may be used to score metal columns.
