Experimental raw data signal acquired in the multiplexed IMS- TOF MS (Agilent) measurement with 1 μM solution of bradykinin, angiotensin I, fibrinopeptide and neurotensin. Multiplexed IMS-TOF raw signal was acquired at 1.6 ns resolution and summed over 1000 IMS acquisitions, corresponding to 127 s. Multiplexed IMS separation encompasses 1270 TOF spectra. Inset shows a small portion of the multiplexed IMS-TOF separation corresponding to a single mass spectrum.
