Student guide: time of flight mass spectrometry example questions and answers One of the methods of ionising samples in time of flight mass spectrometry is by electron impact. How is this ionisation done? [4 marks] A second method of ionising samples in time of flight mass spectrometry is by electrospray ionisation. How is this ionisation done? [4 marks] Which method is most likely to lead to the break up of the ions into fragments? [1 mark] Ionisation by electron impact causes removal of one electron from each particle. Write an equation for the ionisation of each of the following species by loss of one electron.
