EZNo-Vent™GCColumn-MassSpectrometerConnector
• ChangeGC/MS columns inminuteswithout venting—100µm transfer line throttles vacuum and
preventsMS venting.
• Easy to install andmaintain—no special tools or plumbing required.
• Gold-platedbody for inertness.
• Deactivated transfer line keeps analytes focused; high-temperature polyimide ferrules eliminate
leaks at the problematic transfer line fitting.
• Lower cost thanother“no-vent”fittings.
• Available forAgilentGCswith5971/5972or 5973GC/MS andVarian Saturn2000 SeriesMass
Spectrometers.
Wedesigned theEZNo-Vent™GCcolumn-mass spectrometerconnector tobe simpleandeasy touse.
After studying user feedback concerning our EZ-Vent™ 2000 connector, we re-engineered the con-
nector fitting for evenbetterperformance.A critical orifice in theEZNo-Vent™ connectorminimizes
the amount of oxygen allowed into theMS source, eliminating the need for purge gas and enabling
you to skip the lengthy vent and pump-down cycle otherwise required when you make a column
change. This can save nearly a day of downtime with each column change. The EZNo-Vent™ con-
nector easily attaches to theMS source without special tools or extra plumbing. Figure 1 shows the
internal structure of the connector.
