Detectors – Flame Ionization Detector (FID)
Page: 284 User Manual 450-GC Varian, Inc.
Initial Set-Up
To set-up the FID, proceed as follows. Note that when the 450-GC is first
powered up all heated zones with the exception of the column oven are
powered off and all detector electronics are turned off.
1. Refer to the Pre-Installation Instructions for additional information on gas
supply requirements.
2. Press the DETECTOR key on the 450-GC Display/Keyboard to display
the DETECTOR screen. The FID should be listed in position Front ( ),
Middle ( ) or Rear ( ). If your GC is equipped with detector EFC verify the
makeup gas you will be using with your FID.
3. Install a chromatographic column in the GC, on page 13. If the analytical
column is not pre-conditioned, use a no-hole ferrule in the detector column
nut while conditioning the column and leave the detector end of the column
loose in the oven. If the analytical column is pre-conditioned, follow the
usual procedure for column installation.
