Mass spectrometer separates ions based on the :
Answer: C
A mass spectrometer separates ions by their mass to charge ratio (m/z).
Ions are accelerated and then deflected by a magnetic or electric field, or sent through a quadrupole or a flight tube. The path or flight time of each ion depends on its mass divided by its charge, so the instrument sorts ions by m/z and the spectrum is plotted against m/z.
Mass alone, or molecular weight, cannot be the basis, because an ion of mass 100 carrying two charges behaves like an ion of mass 50 carrying one. Charge alone does not separate ions either, since most ions carry a single charge.
