Orbitrap Mass Spectrometer

https://axispharm.com/orbitrap-mass-spectrometer/

The Orbitrap is an ion trap mass analyzer. It consists of two outer electrodes and a central electrode, which enable it to act as both an analyzer and detector. Ions entering the Orbitrap are captured through "electrodynamic squeezing," after which they oscillate around the central electrode and in between the two outer electrodes. Different ions oscillate at different frequencies, resulting in their separation. By measuring the oscillation frequencies induced by ions on the outer electrodes, the mass spectra of the ions are acquired using image current detection. The Orbitrap mass analyzer is a Fourier Transform mass analyzer analog of FT-ion cyclotron resonance (ICR) technology and it has a much smaller instrument size and is easier to operate.
