Problem 10.1

a) Particle impact-induced desorption/ionization methods are numerous in mass spectrometry. Do you know them all?

  1. FAB
  2. SIMS
  3. PD
  4. LSIMS
  5. MBSA
  6. MCI

b) What kind of particles are impacting onto the surface in case of FAB and what kind in LSIMS?

c) Why isn’t PD suitable for magnetic sector analyzers? What type of analyzer is employed instead?

d) Can you draw the basic setup of a FAB or LSIMS ion source?
