Abstract

Abstract Broad-band frequency excitation in Fourier transform mass spectrometry (FT/MS) has previously been achieved via impulse or frequency-sweep time-domain waveforms. In this paper, we introduce pseudo-random-noise excitation based on shift register maximal- length sequences. Experimental FT/MS spectra of perfluorotributylamine excited by pseudo-random noise frequency-sweep excitation are compared. Compared to random-noise excitation, pseudo-random excitation has the advantage of phase-coherence from scan to scan, and thus allows for rapid time-domain signal averaging.
