Technical performance
- The patented design of the device is a combination of a multifunctional sample introduction 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 maximum selectivity compared to existing commercial instruments
