Its due to each isotope (in diatomic form) losing one electron and then also when you get all of the different possible combinations of the three so in the spectrometer you have O2(32) O2(34) O2(36) O2(35) and O2(33) and when each lose an electron you get those specific positive O2 positive ions.
I think this is right, I misread it the first time i thought it just said O+ ions

Ok so from O(17) O(18) and O(16) you need to work out how many diatomic forms of oxygen can be created. So you can get O2 made up of two O(16) atoms to form O2(32) and another made up of O(17) atoms to form O2(34) and another made up of two (O18) atoms to form O2(36).
So now we have O2(32) O2(34) and O2(36) you can also combine different isotopes of oxygen to get a diatomic molecule: so combine O(17) with O(18) you get O2(35) and combine O(16) with O(17) you get O2(33) but if we combine O(16) with O(18) you get O2(34) which is the same as a previous combination and so we discard it
So you end up with O2(34) O2(32) O2(36) O2(35) and O2(33) and all of these form positive (1+) molecules when ionised
