MaOS AxiSpec: Gases and Liquid Analyzer based on Ion Mobility Mass Spectrometry
Technical performance:
• The patented design of the device is a combination of a multifunctional sample intro-
duction and ionization system, drift tube ion mobility spectrometer and sector TOF
mass spectrometer with orthogonal acceleration.
• Multifunction sample introduction and ionization system works with both integrated
ion sources and external available engineering solutions. Integrated ionization
platform allows to use electrospray (ESI), atmosphere pressure chemical ionization
(APCI), atmosphere pressure photoionization (APPI).
• The high-resolution ion mobility spectrometer provides high selectivity compared to existing commercial instruments
Mobility resolving power70 – 120 (measured as td/dt1/2)
