By applying a potential between the sample surface and the mass analyzer, the desorbed secondary ions are extracted into a time-of-flight mass spectrometer, where their masses are separated by flight time, with very high accuracy, based on their mass-to-charge ratio ( m / z ). The focused primary ion beam...
