1Why are samples ionised?
- ATo lose a proton
- BTo create positive ions
- CSo the ions can be accelerated
- DSo that all of the atoms can travel at the same speed
2Atoms are ionised after they are dissolved in a [blank_start]polar[blank_end] solvent. They are then pushed through a nozzle at a [blank_start]high[blank_end] speed. Once they are ionised, the sample then consists of [blank_start]positive[blank_end] ions.
- Anon-polar
- Bpolar
- Cpositive
- Dneutral
- Ehigh
- Flow
- Gnormal
- Helectrical
- Inegative
- Jpositive
3What happens during acceleration?
- AAn electric field accelerates positive ions
- BElectricity accelerates negative ions
- CIons move at a constant speed
- DIons are given the same kinetic energy
4Ions leave the electric field with a constant speed and a constant kinetic energy.
- ARichtig
- BFalsch
5During ion drift, the region that the ions enter has [blank_start]no[blank_end] electric field and they drift through this at [blank_start]the same[blank_end] speed after acceleration.
- Ano
- Bsome
- Ca positive
- Da negative
- Ea lot of
- Fa higher
- Ga lower
- Hthe same
6Ions must be charged in order for them to be accelerated.
- ARichtig
- BFalsch
