Particle transmission efficiency of ES using a VUV ionizer with different nozzle geometries: a grinded capillary that produces a single Taylor cone and a 3D-printed `twin nozzle' featuring two separate openings, each generating its own Taylor cone. (a) Schematic of the ground nozzle. (b) Schematic of the twin nozzle with dual openings. (c) Particle counts using the Rayleigh scattering setup. (d) Particle counts using SMPS. |
