Question

In mass spectrometer, the ions are sorted out in which of the following ways?

(a) By accelerating them through electric field

(b) By accelerating them through magnetic field

(c) By accelerating them through electric and magnetic field

(d) By applying a high voltage

This question was addressed to me in an interview.

I need to ask this question from Principle of operation of Mass Spectrometer in chapter Mass Spectrometer of Analytical Instrumentation

Answer 1

Right option is (c) By accelerating them through electric and magnetic field

To explain I would say: In mass spectrometer, the ions are sorted out by accelerating them through an electric and magnetic field. A record of number of different kinds of ions is called mass spectrum.
