5 minute GC-MS column changeover
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:
