ABSTRACT:
The measuring process for generating mass spectra using a sequentially-scanned quadrupole ion trap mass spectrometer, is improved by controlling the measurement of the ion packages ejected from the ion trap so that measurement takes place starting at the anticipated exit times of the ion packages and measurement continues only as far as possible for a time duration corresponding to the length of the ion packages. Measuring only during ion package ejection enables a measurement for the total number of ejected ions having a selected mass to be obtained by means of digital addition of the individual package measurements. Subsequent processing of the data can be carried out with practically only the fluctuations of normal ion counting statistics.
