    State what is adjusted in the mass spectrometer in order to direct ions with different m/z values onto the detector. Explain your answer. (3 Marks)

    I understand that it's the magnetic field strength that is adjusted.
    My reason: To allow the ions to enter the detector in order of increasing mass?

    Answer:
    Magnetic/electric field
    Correct link between deflection and m/z
    Correct link between deflection and field

    Does this last part literally mean, the stronger the field the more the deflection? Please can somebody write me a model answer. Thanks.

    Yes it does.

    Increasing the strength of the magnetic field will increase deflection. A lower m/z will be deflected more than a higher m/z.

    What paper was this in?

    And pretty sure the guy above me summed it up :P

    I would say:
    for Mark1 - the electromagnetic field is adjusted
    for Mark2 - The stronger the magnetic field, the stronger the deflection
    and not sure about Mark3
