Paramagnetic analyser

Principle

Oxgen and nitric oxide are paramagnetic

  • because the electrons in the outer shell of the molecule are unpaired
  • thus attracted into a magnetic field

Most other gases (e.g. nitrogen) are weakly diamagnetic and thus are repelled from a magnetic field.

Advantage

  • Rapid

Disadvantage

  • Frequent calibration required
  • Interfered by water vapour
Keywords Oxygen, measurement of ; Paramagnetic analysis
