Question

In quadrupole mass spectrometer, the ratio u/v is mass dependent, where ‘u’ is the DC voltage and ‘v’ is the peak amplitude.

(a) True

(b) False

I had been asked this question in an interview for job.

I want to ask this question from Quadrupole Mass Spectrometer topic in section Mass Spectrometer of Analytical Instrumentation

Answer 1

Correct answer is (b) False

Explanation: In quadrupole mass spectrometer, the ratio u/v is mass independent, where ‘u’ is the DC voltage and ‘v’ is the peak amplitude. This ratio is kept constant.
