In electron impact mass spectrometry (EIMS),what is being detected?
A)The molecular mass of the compound
B)The molecular formula of the compound
C)The mass to charge ratio of any ionic species
D)The mass to charge ratio of any neutral species

Question

Quizplus · Accepted Answer

In electron impact mass spectrometry (EIMS), the detector measures the mass to charge ratio (m/z) of ionized species. The technique does not directly detect neutral species, nor does it provide the molecular formula or the molecular mass of the compound without further analysis and interpretation of the mass spectrum.
