Below is listed a set of conditions which might exist in an imagined mass spectrometry experiment. i) The electron beam inside the ionisation chamber must be of low enough energy for an electron to be captured by M to give M ii) The electron beam inside the ionisation chamber must be of high enough energy M to be ionised to give M +
iii) The magnetic field in the mass analyser must be high enough to allow ions M +
and higher through to the detector iv) The sample must be reasonably volatile Which ONE of the following sets of conditions is desirable for a successful experiment? A. i), ii) and iii) B. ii) and iv) C. ii) and iii) D. i) and iii) E. i), iii) and iv)
