Study Notes
Mass Spectrometry
- A mass spectrometer generates charged molecules or fragments of an analyte in a gas phase.
- The objective of a mass spectrometer is to ionize a gas phase molecule and analyze the masses of its produced ions.
Ionization
- Ions are electrically charged atoms or groups of atoms formed when atoms lose or gain electrons.
- Atoms can become negatively charged (gain electrons) or positively charged (lose electrons) ions.
Separation and Detection
- Produced ions are separated according to their mass-to-charge ratio (m/z).
- The relative abundance of each ionic species present is recorded (measured) after separation.
