Abstract
A mass spectrometer including: an ionization chamber () that generates ions from a sample, a collision cell () located downstream from the ionization chamber (), a mass separation unit () located downstream from the collision cell (), an energy barrier unit () located between the collision cell () and the mass separation unit (), a voltage application unit () that applies a voltage to each of the ionization chamber (), the collision cell (), and the energy barrier unit (), and a control unit () that controls the voltage application unit () such that a potential of the ionization chamber () is set to a first potential, a potential of the collision cell () is set to a second potential that is lower than the first potential, and a potential of the energy barrier unit () is set to a third potential between the first potential and the second potential.
