Question

The principle behind the ionisation detector is:

a. Incident radition impaction on electrodes generates a current, which is measured.

b. The ions and electrons generated by the interaction of incident radiation and gas atoms at

low pressure migrate to polarised electrodes, creating a current, which is measured.

c. Incident radiation promotes electrons to the conduction band of a semiconducting

electrode, generating a current, which is measured.

d. Incident radiation promotes electrons to the valence band of a semiconducting electrode,

generating a current, which is measured.

e. Incident radiation interacts with gas phase atoms which are accelerated to a metal

cathode, sputtering metal ions into the gas phase, and these generate a current, which is

measured.

Explanation / Answer

Answer (e)

Incident radiation interacts with gas phase atoms which are accelerated to a metal

cathode, sputtering metal ions into the gas phase, and these generate a current, which is

measured.
