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.
