Experimental evaluation of peak drift and mass number mesurement in a mass spectrometer

The results of experimental studies of the peak drift dynamics and techniques of automatic measurement of mass numbers are given. A mass spectrometer system consisting of a commercial mass spectrometer МХ-7304А, personal computer IBM PC, digital-to-analog and analog-to-digital converters is used. The error of mass number measurement by the developed technique does not exceed 0.01 %.
