Question

Describe the principle of mass spectrometry.

Answer 1

Answer:
Mass spectrometry is an analytical technique which is based on ionizing chemical species and sorting the ions based on their mass-to-charge ratio.
Analytical process passes several stages:
- Ionization – an atom/molecule is ionized by knocking electrons off to give a positive ion;
- Acceleration – in order to have the same kinetic energy ions are accelerated;
- Deflection – ions are deflected by a magnetic field according to their mass;
- Detection – the beam of ions passing the apparatus is being detected.
