Frequently Asked Questions

What is the function of the critical orifice in the
EZ-No-Vent™ GC Column-Mass Spectrometer Connector?

The 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™ GC Column-Mass Spectrometer Connector is available for Agilent GCs with 5971/5972 or 5973 GC/MS and Varian Saturn 2000 Series Mass Spectrometers.
