Quadrupole time-of-flight mass spectrometry

Definition: A type of mass spectrometry where the mass-to-charge ratio of the sample ions is measured whilst the ions are held in a stable orbit by an electric field generated by four parallel electrodes. The sample ions with different masses are accelerated to the same (known) kinetic energy and the time taken for each ion to reach a detector at a known distance is measured.
