EZNo-Vent™GCColumn-MSConnector
Change Columns inMinutesWithout Venting
byDonna Lidgett, GCAccessories ProductMarketingManager
•Save hours of downtime—100µm transfer line throttles vacuum and preventsMS pump-
down.
•Easy to install andmaintain—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 GCswith 5971/5972 or 5973GC/MS, Varian Saturn 2000 SeriesMSs.
We designed the EZNo-Vent
™
connector to be
simple and easy to use. A critical orifice in
the EZNo-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 requiredwhen
youmake a column change.This can save
nearly a day of downtimewith each column
change.The EZNo-Vent
™
connector easily
attaches to theMS sourcewithout special
tools or extra plumbing.
