Abstract:

We describe the technique by which the intensity of spectral lines can be evaluated and the global maxima of the mass-spectrum peaks under the influence of pulse interferences can be defined using an experimental setup based on a commercial MX-7304A mass spectrometer, IBM personal computer (PC), and a digital extremum regulator that allows one to ignore local extrema and bring about automatic search for a global maximum of the mass-spectrum peak and its tracking with an accuracy of 0.0012% at a speed of response of 50 kHz, elevated speeds of the scanning of masses 500 amu/sec, and stability of regulation.

Keywords: spectral line intensity; mass spectrum; local and global extrema; extremum regulator
