Electrospray ionisation time-of-flight mass spectrometry

Definition: A type of mass spectrometry where the sample is ionised by forcing a solution (usually in an organic solvent) of the sample through a small heated capillary (at a flow rate of 1--10 L min-1) into an electric field to produce a very fine mist of charged droplets and where 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. This time is dependent on the mass-to-charge ratio of the ion.
