A linear ion trap component of a mass spectrometer. An ion trap mass spectrometer may incorporate a Penning trap (Fourier-transform ion cyclotron resonance), [12] Paul trap [13] or the Kingdon trap. [14] The Orbitrap, introduced in 2005, is based on the Kingdon trap. [15] Other types of mass spectrometers may also use a linear quadrupole ion ...
A Thermo Finnigan LTQ (linear trap quadrupole) The linear ion trap (LIT) is a type of ion trap mass spectrometer. In a LIT, ions are confined radially by a two-dimensional radio frequency (RF) field, and axially by stopping potentials applied to end electrodes. LITs have high injection efficiencies and high ion storage capacities. [1]
Ion trajectories in an Orbitrap mass spectrometer. In mass spectrometry, Orbitrap is an ion trap mass analyzer consisting of an outer barrel-like electrode and a coaxial inner spindle-like electrode that traps ions in an orbital motion around the spindle.
In experimental physics, a quadrupole ion trap or paul trap is a type of ion trap that uses dynamic electric fields to trap charged particles. They are also called radio frequency (RF) traps or Paul traps in honor of Wolfgang Paul , who invented the device [ 1 ] [ 2 ] and shared the Nobel Prize in Physics in 1989 for this work. [ 3 ]
The cylindrical ion trap mass spectrometer (CIT) is a derivative of the quadrupole ion trap where the electrodes are formed from flat rings rather than hyperbolic shaped electrodes. The architecture lends itself well to miniaturization because as the size of a trap is reduced, the shape of the electric field near the center of the trap, the ...
Linear ion trap – Fourier-transform ion cyclotron resonance mass spectrometer (panels around magnet are missing) The physics of FTICR is similar to that of a cyclotron at least in the first approximation. In the simplest idealized form, the relationship between the cyclotron frequency and the mass-to-charge ratio is given by
