Post in Orbitrap Exploris 480 on nitrogen generator or tanks?: ABRF Discussion Forum: ABRF Discussion Forums

Hi all, We have an Orbitrap Exploris 480 on the Peak nitrogen generator sold to us by Thermo. However, we’re hearing from other sources that the nitrogen generator will not produce clean nitrogen more than a few months, and we should be using compressed nitrogen tanks instead. So I have two questions: 1. Is your Orbi on tanks or a nitrogen generator? 2. If you are using a nitrogen generator, have you experienced any problems due to dirty nitrogen? Thanks! Kristina Nelson
