Study Notes
Mass Spectrometry
- Mass spectrometry is a technique used to measure the relative masses of different particles
- Charged particles are affected by electric and magnetic fields
- Charged particles are created from atoms in matter, either by losing or gaining electrons
- Atoms can have excess positive or negative charges
- Ions are formed when an atom loses or gains electrons
- The experiments using charged particles in electric and magnetic fields were conducted in the early days of scientists studying atoms
- The technique separates charged particles with different masses
- Relative masses of particles are measured indirectly
- The instrument (mass spectrometer) can also measure relative charges
- All substances contain atoms in one form or another
- Atoms contain protons and electrons with positive and negative charges, respectively
