The measurements of the viscosity of the solutions were performed in a shear rate range of 0.01–1000 s −1 by using a rheometer (HAAKE Rheo Stress 600).
WebIn the MS method editor, each colored bar represents a different data-collection function. The green bar repre-sents the solvent delay; up to 4 solvent delays can be placed throughout the run. During solvent delay, the filament current is off. The blue bar represents a full-scan function; the available mass range for full scan is m/z 1-1200.
