Frage 1
Frage
Why are samples ionised?
Antworten
-
To lose a proton
-
To create positive ions
-
So the ions can be accelerated
-
So that all of the atoms can travel at the same speed
Frage 2
Frage
Atoms 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.

Frage 3
Frage
What happens during acceleration?
Antworten
-
An electric field accelerates positive ions
-
Electricity accelerates negative ions
-
Ions move at a constant speed
-
Ions are given the same kinetic energy
Frage 4
Frage
Ions leave the electric field with a constant speed and a constant kinetic energy.
Antworten
- True
- False
Frage 5
Frage
During 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.

a lower
-
the same
Frage 6
Frage

Antworten
- True
- False
