(b) It has great sensitivity

(c) It is suitable for data storage

(d) It is suitable for library retrieval

I had been asked this question at a job interview.

This intriguing question comes from Principle of operation of Mass Spectrometer topic in section Mass Spectrometer of Analytical Instrumentation

Answer 1

Right choice is (a) Impurities of masses different from the one being analysed interferes with the result

For explanation I would say: Impurities of masses different from the one being analysed does not interfere with the result in mass spectroscopy. This is a major advantage of this technique.
