A
Key Concept
Ion manipulation by electromagnetic fields
Explanation
Ions are charged particles that can be manipulated by electromagnetic fields within a mass spectrometer to separate them according to their mass-to-charge ratio (m/zm/z). This is essential for the operation of the mass spectrometer and the accurate determination of the masses of the ions.
