EZ No-Vent® GC Column-Mass Spectrometer Connector
for Bruker/Varian Saturn 2000 Series Mass Spectrometers
• Change GC-MS columns in minutes without venting—100 µm transfer line
maintains vacuum and prevents venting.
• Easy to install and maintain—no special tools or plumbing required.
• Gold-plated body for inertness.
• High-temperature polyimide ferrules eliminate leaks at the problematic transfer
line fitting.
• Lower cost than other “no-vent” fittings.
We designed the EZ No-Vent® GC column-mass spectrometer connector to be simple
and easy to use. A critical orifice in the EZ No-Vent® connector minimizes the amount
of oxygen allowed into the MS source, eliminating the need for purge gas as is required
for other manufacturers’ vent systems. This enables you to skip the lengthy vent and
pump-down cycle otherwise required when you make a column change, saving nearly
a day of downtime with each column change. The EZ No-Vent® connector easily at-
taches to the MS source without special tools or extra plumbing.

Figure 1: The EZ No-Vent® connector incorporates
a laser- machined orifice for optimal flow through
the fitting. Coupled with the 100 µm ID transfer line,
it minimizes the amount of oxygen entering the MS,
which eliminates the need for purge gases.
