Each image in Figure A.4 shows a stroboscopic sequence of a 5 nL DMSO
droplet ejection. Each 5 nL (212 μm diameter) droplet is traveling upward
at approximately 1 m/s to a glass slide. In each of the four images, the
droplet has been photographically captured at six points in time by a multi-
flash strobe at intervals of 400 μs. The four images show 1, 20, 40, and
100 drops deposited on the slide.
