Make the ElCD/PID Series Connection
Use the following procedure to make the ElCD/PID series connection. After you make this
connection, you can operate either the ElCD or the PID without any loss of sensitivity.
NOTE : Always connect the analytical column to the PID, and the PID exit tube to the ElCD.
1. Cut a length of the supplied deactivated 0.53-mm. I.D. fused silica tubing (P/N N930-
1358) long enough to connect the PID exit line to the ElCD. Try to use the shortest
possible length (approximately 12 inches).
2. nsert a 1/16-in. column nut and a 1/16-in. graphite/Vespel ferrule
(P/N 0992-0301) over one end of the cut fused-silica tubing. Make sure the tapered
end of the ferrule faces the nut as shown below.

3. Cut about 1 cm (3/8 inch) from the end of the fused-silica tubing using a wafer scribe
(P/N N930-1386, pkg. of 10 scribes) or other column cutting tool. Break off the tubing
at the score mark and make sure that the break is clean and square. Examine the cut
with a magnifying glass and compare it to the examples below.
