摘要： This mass spectrometer is provided with an ion guide (37) having a multipole rod electrode (1), a power source unit (5) for applying voltage to the multipole rod electrode, and a control unit for controlling the power source unit, said mass spectrometer being characterised by the multipole rod electrode having a rod electrode divided into a plurality of segmented rods (2A-1, 2A-2, 2B-1, 2B-2, 2C-1, 2C-2, 2D-1, 2D-2) at mutually different positions in the axial direction. Thus enabled is low-cost, high-throughput analysis.
