Figure 1
(A) Schematic drawing of our vacuum compatible GDSJ nozzle with color-coded labeling used to highlight internal gas and liquid channels. The length (- - -) and width (···) of the primary liquid sheet are defined. The jet speed can also be inferred by using droplets formed from Rayleigh-plateau instability. (B) CAD model of the GDSJ nozzle developed by the ASU group with channel dimensions in micrometres. The central inlet delivers the liquid sample, while the impinging gas line forms the sheet, and the sheath gas ensures stable operation in vacuum conditions. (C) Microscope image of the 3D-printed nozzle (white scale bar represents 0.5 mm). The Uppsala nozzle design is provided in Supporting Fig. 1. Both designs are publicly available online.
