5975 Series MSD Operation Manual 43
To install a capillary column in the GC/MSD interface
Agilent 7890A and 7820A, and 6890 GCs
Materials needed
• Column cutter, ceramic (5181-8836) or diamond (5183-4620)
• Ferrules
• 0.3-mm id, for 0.10-mm id columns (5062-3507)
• 0.4-mm id, for 0.20- and 0.25-mm id columns (5062-3508)
• 0.5-mm id, for 0.32-mm id columns (5062-3506)
• 0.8-mm id, for 0.53-mm id columns (5062-3512)
• Flashlight
• Hand lens (magnifying loupe)

Procedure
1 Condition the column (page 41).
2 Vent the MSD (page 82) and open the analyzer chamber (page 84). Be sure
you can see the end of the GC/MSD interface.
3 If the CI interface is installed, remove the spring-loaded tip seal from the
MSD end of the interface.
4 Slide an interface nut and conditioned ferrule onto the free end of the GC
column. The tapered end of the ferrule must point towards the nut.
CAUTION
Note that the column installation procedure for the 5975 Series MSDs is different from
that for most previous MSDs. Using the procedure from another instrument may result
in poor sensitivity and possible damage to the MSD.
