Question

All the ions entering the tube have the same kinetic energy.

(a) True

(b) False

This question was addressed to me in an online interview.

This is a very interesting question from Time of Flight Mass Spectrometer topic in section Mass Spectrometer of Analytical Instrumentation

Answer 1

Right choice is (a) True

To explain I would say: Separation of ions occurs while they are moving from the ion source to the detector. All the ions entering the tube have the same kinetic energy.
