Orbitrap قصص

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.

It combines high selectivity and efficiency of transfer for selected ions, along with ultrahigh resolving power and acquisition rates of up to 20 Hz for both Orbitrap and linear ion trap MSn analyses. The tribrid architecture includes a quadrupole mass filter, linear ion trap and an Orbitrap mass analyzer, and the high degree of parallelization of these operations achieves a maximally efficient duty cycle.
