Abstract
A time-of-flight mass spectrometers, in which the ions are generated by ionization of analyte substances on a sample support, by matrix-assisted laser desorption (MALDI). The time-of-flight mass spectrometer consists of using space-adjusting actuators to set the spacing of the sample support from the nearest acceleration electrode so that the flight time of ions of a reference substance prescribed by the calibration can be precisely adjusted. Due to this adjustment of the spacing, a once only calibration of the relationship between the flight time and mass (i.e. the mass scale) may be constantly retained.
