(1) In the time-of-flight mass analyzer, lighter ions travel more quickly than heavier ions.

(2) The Orbitrap analyzer is a high-resolution mass analyzer that require a magnetic field.

(3) In the quadrupole mass analyzer, an electric field deflects ions in complex trajectories as they migrate toward the detector.

(4) The high-resolution FT-ICR analyzer does not require a magnetic field.

(5) In the linear quadrupole ion trap, manipulating voltages allows ions of a specific mlz to be expelled from the ion trap. Your answer:
