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.

 
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.
 
Time-of-Flight type
The time required to fly a fixed distance depends on the mass and is utilized to separate various masses.
