    High Mass spectrometry:
    On a mass spectrum of a high mass spectrometry, the abundance of ions wouldn't be relative but exact, right?

    what does this mean? Ions strike a detector, accept electrons, lose their charge and create a current which is proportional to the abundance of each ion.

    So lets say the current is 10A will the abundance me 10%?

    Also, explain m/z to me? why is mass always 1?

    Lastly, acceleration - are the positive ions propelled by a positive plate, focused to form of a beam of ions and them attracted to a negative plate to keep it accelerating? My chemistry doesn't mention a positive and a negative plate..just a negative plate...

    ..
    m/z mass is not always 1 - it is as accurate as the mass spectrometer and could have 16 decimal places (or more)

    I think you mean charge here, not mass. Mass depends on the species/molecule/fragment you are looking at (which indeed is the point!). Charge, however, is usually 1 (since it's generally the ionisation of just one electron)
