MS of C60 obtained using two amplifiers with identical instrument settings on a MALDI-FTMS. Input referred baseline noise is shown in the inset. MS acquired with BUSM transimpedance amplifier powered by switching power supplies in panel B, has ≈ 25 fold reduction in noise as compared to that of commercial amplifier in panel A. Panel C shows the complete broadband m/z range of the MS in panel B using the BUSM amplifier.
