What is the ms NoVent II?
The ms NoVent II is designed to allow column, liner or septum changeover, or column maintenance to be carried out, without the need to shut down the MS.

How does the ms NoVent II work?
The ms NoVent II is a fluidic valve. The unique design ensures a helium purge maintains a positive flow from the valve to the atmosphere, when a column is not connected. The valve prevents air entering the MS.

The retrofitted ms NoVent II requires:

  1. A Control Unit (same for all GC’s)
  2. The correct tee for your GC
  3. The correct restrictor for your GC (note that for some systems, an adaptor is also supplied with the restrictors)

All three items must be ordered to have a complete ms NoVent II system.
