5 minute GC/MS Column Changeover
•
Change GC columns without venting the MS
•
Isolates MS while the GC column is being changed
•
Prevents air from entering the MS by using an
innovative helium purge system
•
Restricts gas flow into the MS using a restricted
transfer line specific to the MS pumping system
•
Improves MS productivity
•
Reduce MS downtime
•
Available for Agilent,Varian and Shimadzu systems
T
he ms-NoVent allows a capillary column to be changed without venting the MS and the mass spectrometer can be
operational almost immediately. The ms-NoVent prevents air and water from entering the MS during column change-over. The
key to the ms-NoVent is the unique Flow Director Orifice and deactivated fused silica interface tube, which are located at the
MS inter face as part of the ms-NoVent Tee.
Before the column is removed from the interface, a helium purge is turned on. The fused silica restrictor/interface tube limits the flow
of helium into the mass spectrometer. As shown in
Figure 1
, after the column has been removed from the ms-NoVent Tee, the Flow
Director Orifice prevents air from entering the mass spectrometer. Thus, the flow of helium through the orifice acts as a dynamic seal
preventing air being sucked back into the MS.
Normal Operation Mode
In normal operation mode the Helium purge is turned
off. The column flow is directed through to the MS via the
fused silica transfer tube. (See
Figure 2
)
Column Change Mode
In the column change mode a Helium purge is applied
to the Interface Tee. the column can then be disconnected
without shutting down or ‘venting’ the MS. The existing col-
umn, or a new column, can then be connected and the ms-
NoVent switched back to normal mode for standard opera-
tion. (See
Figure 3
)
