    1. BASIC MASS SPECTROMETRY

    Magnetic field Sector type

    Ions travel in a circular orbit within a magnet but the radius of the orbit is different depending on the ion mass. This difference is utilized to separate various masses.

    Magnetic Sector Mass Spectrometer
    Quadrupole type

    RF and DC voltages are overlapped and applied to 4 rods. While ions traveling between the rods oscillate, the oscillating orbit is different depending on the mass. This difference is utilized to separate various masses.
