ABSTRACT:
A method is described for operating a mass spectrometer with a location-resolving detector. In this case, when an ion impinges on the detector, the instantaneous parameters of the analyzer are read and compared with a calibration table, and the instantaneous mass value (to be expected) is determined therefrom in the center of the detector. The location signal of the detector indicates the impingement location of the recorded event and is converted, via a second calibration table, into the deviation of the actual mass from the mean mass. The exact (actual) mass value is calculated from both values. This value is recorded in a memory of a computer.
