Massive‐cluster impact is demonstrated to be an effective ionization technique for the mass analysis of proteins as large as 17 kDa. The design of the cluster source permits coupling to both magnetic‐sector and quadrupole mass spectrometers. Mass spectra are characterized by the almost total absence of chemical background and a predominance of multiply charged ions formed from 100% glycerol matrix. The number of charge states produced by the technique is observed to range from +3 to +9 for chicken egg lysozyme (14 310 Da). The lowerm/zvalues provided by higher charge states increase the effective mass range of analyses performed with conventional ionization by fast‐atom bombardment or liquid secondary ion mass spectrometry.
