Segmented Planar Calibration for Correction of Errors in Time of Flight Mass Spectrometers

摘要

An ion detector system for a mass spectrometer is disclosed comprising an ion detector comprising an array of detector elements. The ion detector system is arranged to correct for tilt and non-linear aberrations in an isochronous plane of ions. The ion detector system generates separate first mass spectral data sets for each detector element and then applies a calibration coefficient to each of the first mass spectral data sets to produce a plurality of second calibrated mass spectral data sets. The plurality of second calibrated mass spectral data sets are then combined to form a composite mass spectral data set.
