2.8 Instrumental Analysis

Question 1

Ionisation

Answer 1

Beam of electrons knock an electron from atoms or molecules in sample

Question 2

Acceleration

Answer 2

Ions are accelerated and have same kinetic energy

Question 3

Deflection

Answer 3

Ions deflected via magnetic field based on their mass to charge ratio (m/z)

Question 4

Detection

Answer 4

Ions detected by detector ions and create a current which is proportional to the abundance of the ion
