Gaseous molecules enter the ion source where they are ionized through collision with electrons. Ions are accelerated out of the ion source and into the analyzer tube all with the same kinetic energy by a voltage applied between the ion acceleration plates. The ions encounter a magnetic field applied perpendicular to the direction of travel. The magnetic field deflects the ions on a circular path,with a radius that is dependent on the m/z of the ions,towards the detector at the end of the analyser tube. ions deflected on a circular path with a radius equal to the radius of curvature will travel through the slit leading to the detector. heavier ions are deflected enough and lighter ones are deflected too much to reach the detector. A mass spectrum is created by varying the magnetic field strength, therefore altering which ions reach the detector.
