Nanometre-sized droplets from a gas dynamic virtual nozzle
This paper reports on improved techniques to create and characterize
nanometre-sized droplets from dilute aqueous solutions by using a gas dynamic
virtual nozzle (GDVN). It describes a method to measure the size distribution of
uncharged droplets, using an environmental scanning electron microscope, and
provides theoretical models for the droplet sizes created. The results show that
droplet sizes can be tuned by adjusting the gas and liquid flow rates in the
GDVN, and at the lowest liquid flow rates, the size of the water droplets peaks at
about 120 nm. This droplet size is similar to droplet sizes produced by
electrospray ionization but requires neither electrolytes nor charging of the
solution. The results presented here identify a new operational regime for
GDVNs and show that predictable droplet sizes, comparable to those obtained
by electrospray ionization, can be produced by purely mechanical means in
GDVNs.Ministerio de Economía, Industria y Competitividad, Plan Estatal 2013–2016 Proyecto Retos DPI2016-78887-C3-1-
