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, making the measurements of mass-to-charge ratio very accurate when using this type of mass analyzer. This module will discuss the theory and practice of using magnetic sector mass analyzers.

Topics include:

Equations of ion motion
Data acquisition modes
Electrostatic analyzers
Double focusing instruments
Ion optics
Performance limitations
Mass resolution and accuracy
