Mass Spectrometry Flashcards
1
Q
Explain what occurs when using the Electron impact method (EIMS)
A
A vaporized sample is bombarded with electrons
It results in extensive fragmentation
2
Q
What occurs when using the chemical ionization method (CIMS)?
A
The vapourized sample is mixed with a charged reagent gas
This causes some fragmentation
3
Q
What occurs when using the Fast Atom Bombardment (FAB) method?
A
The sample (solution/suspension) is bombarded with inert gas atoms
