ABSTRACT:
A chopped molecular beam mass spectrometry measuring system (11, 12, 13, 14, 20) has its measurement time multiplexed (25, 26). The chopping of the molecular beam is synchronized with the multiplexing (chopper 21, OR gate 32, phase detector 35 and voltage controlled oscillator 36). Means 34 are provided for phase shifting the chopper 21 with respect to the multiplexing. A four channel amplifier 26 (disclosed in detail in FIGS. 3 and 4) is provided for independently varying the baseline and the amplitude in each channel of the multiplexing.
