Data for the infusion of droplets containing egg white in aqueous ammonium acetate solution (1 M) obtained using TWIMS Q-TOF instrumentation. (A) Total ion chromatogram of infused egg white droplets; 100 scans equivalent to ∼2.6 s are shown (MS total cycle time = 0.026 s/scan). (B) Mass spectrum (unmodified) obtained for the infusion of egg white droplets upon combining ∼8 min of acquisition. Ovalbumin protein (44 kDa) from egg white has been identified in the spectrum with the major charge states of ovalbumin monomer (12+ and 13+) indicated.
