Magnetic Sector Mass Analyzers

Magnet/electric sector instruments are employed for mass analysis using the principle that charged species can be deflected in magnetic and electric fields. The degree of ion deflection in a magnetic field is proportional to the square root of their m/z ratio and the potential through which they are accelerated prior to mass analysis; this makes the measurement of mass-to-charge ratio very accurate when using this type of mass analyzer.
