Venting the TSQ 9000 Mass Spectrometer
Vent Valve Knob
CAUTION - INSTRUMENT DAMAGE
Do not proceed until the instrument is vented, or
pieces of the column or ferrule might blow into the instrument. To ensure that the
instrument is vented, check how much the glass cover compresses the top cover o-ring in
the manifold. Once the o-ring surface touching the glass is about 1 mm, it is safe to open
the instrument and remove the column.
Note
Remove the screws completely so that they do not scratch the manifold when you
close the door.
