MAX-QMS flange mounted system
The Extrel MAX Systems are UHV-compatible flange mounted quadrupole mass spectrometers. The ionizer, quadrupole mass filter, and detector on a mounting flange are designed for inclusion in your exprimental vacuum chamber. The electronics consist of the rack mountable QCi (Quadrupole Control, integrated) quadrupole mass filter power supply and a Merlin CS (Command System). The Merlin mass spectrometer controller software completes the system.
The MAX Systems are based on Extrel’s industry-leading mass spectrometer technology centered on our range of RF power supplies, and our 9.5 mm and 19 mm trifilter mass filters. With a broad range of capabilities and available options, as well as Extrel’s ability to provide customer designs, the MAX Systems can be configured for an extensive variety of applications.
