Chp 3 The Mass Spectrometer

Question 1

Vaporisation

Answer 1

Sample is heated to convert it to a gas

Question 2

Ionisation

Answer 2

Electron gun to knock an electron out of the atom to produce a positive ion

Question 3

Acceleration

Answer 3

Using oppositely charged plates to accelerate ions down the tube

Question 4

Seperation

Answer 4

1. Ion is too heavy relative to the magnetic field and it collides with the far wall
2. The ion is too light relative to the strength of the magnetic field and it collides with the near wall
3. The mass to charge ration of the ion matches the magnetic field and the ion is directed towards the detector

Question 5

Detection

Answer 5

The detector counts the number of each ion with a given mass
