Question

The DC ion accelerating voltage is swept from _________

(a) 0 to 50 V

(b) 50 to 100 V

(c) 200 to 300 V

(d) 50 to 250 V

I have been asked this question at a job interview.

Question is from Radiofrequency Mass Spectrometer in chapter Mass Spectrometer of Analytical Instrumentation

Answer 1

The correct answer is (d) 50 to 250 V

For explanation I would say: The DC ion accelerating voltage is swept from 50 to 250 V. This is done twice per second.
