(a) Droplet diameters achieved as a function of applied liquid flow rate Q for different conductivities K. (b) In the dimensionless parametrization of the flow rate and droplet (Maißer et al., 2013 ▸), the droplet diameters from the different conductivities fall on the same curve. (c) A side-view microscopy image (0.92 µm pixel size) of the 2PP-3D printed CCT. The 40 µm ID of the electrospray tip exactly matches the ID of the utilized fused silica capillary and the 30° angle at the tip is seamlessly transferred to the angle of the formed liquid cone. The tip–liquid interface is indicated with the dotted red line.
