Changing a Column
This procedure outlines the steps required to properly position the end of the column in
the Source and connect the column to the MS Transfer Line tube fitting inside the GC
oven.
CAUTION
ATTENTION
To prevent contamination of the mass spectrometer, always wear clean,
lint-free, powder-free nitrile
, nylon, or PVC gloves when handling the
part of the capillary column that will be inserted into the MS Transfer
Line. Never touch these parts with ungloved (bare) fingers, as this will
introduce contaminants into the system.
Pour éviter la contamination du spectromètre de masse, porter toujours
des gants de nitrile, de nylon ou de PVC propres, exempts de peluches
et sans poudre lors de la manipulation de la partie de la colonne
capillaire qui sera insérée dans la ligne de transfert MS. Ne touchez
jamais ces pièces avec des doigts non agglomérés, car cela introduira
des contaminants dans le système.
Tools and Items Required:
NOTE: Do not use a 100% Graphite ferrule to connect the column since it is a porous
material that will allow air to diffuse into the MS system and prevent a high vacuum
from being attained inside the system.
•
9/16 inch wrench
•
1/4 inch wrench
•
5 mm wrench
•
One 1/16 inch Column Nut
•
One Graphite/Vespel ferrule appropriately sized for the capillary column i.d.
that you will be using. (</= 0.25 mm i.d. columns require a 0.4 mm i.d. ferrule
and >/= 0.32 mm i.d columns require a 0.5 mm i.d. ferrule.)
•
Optional Plug Handle and Sight (P/N N6480380)
NOTE: Please read the following guidelines in entirety prior to attempting the procedure for
the first time. Following these guidelines at all times when performing this procedure
will ensure that contaminants entering your MS system will be minimized, vacuum
leaks will be minimized and detector response (sensitivity) will be maximized.
