Figure 3:
Full scans and surface-induced dissociation spectra of hexameric (a) HFQ65 and (b) HFQ102 using the Gen 3 device on the FT-ICR. The four bottom spectra are zoomed in to show the isotopic resolution of the 15 T ICR using a 9 s transient. The SID spectra are an average of 30 scans at 4 M transient length (low m/z 1,000); the full scans are an average of 10 at 1 M transient length. M = monomer, D = dimer, T = trimer, Q = tetramer, P = pentamer, H = hexamer
