EZ No-Vent™ GC Column-MS Connector
Change Columns in Minutes Without Venting
by Donna Lidgett, GC Accessories Product Marketing Manager
•Save hours of downtime—100µm transfer line throttles vacuum and prevents MS pump-
down.
• Easy to install and maintain—no special tools or plumbing required.
•Gold-plated body for inertness.
•Deactivated transfer line keeps analytes focused; high-temperature polyimide ferrules
eliminate leaks at the problematic transfer line fitting.
• Lower cost than other “no-vent” fittings.
•Available for Agilent GCs with 5971/5972 or 5973 GC/MS, Varian Saturn 2000 Series MSs.
We designed the EZ No-Vent™ 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
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 EZ No-Vent™ connector easily
attaches to the MS source without special
tools or extra plumbing.
