mass spectrometry Flashcards
1
Q
sample inlet
A
gases/liquids are injected but solids are heated to vaporise them
2
Q
ionisation area
A
heated element produces high energy electrons- these are bombarded at any atoms/molecules in the sample and knock electrons out- cations are formed of the sample
3
Q
acceleration area
A
an electric field is used to accelerate the ions so they all have the same kinetic energy
4
Q
drift region
A
vacuum- no air molecules for ions to collide with as it would change their direction
