Electrospray droplet sources for thin film deposition
Electrospraying utilises electrical forces for liquid atomisation. Droplets obtained by this method are highly charged to a fraction of the Rayleigh limit. The advantage of electrospraying is that the droplets can be extremely small, down to the order of 10’s nanometres, and the charge and size of the droplets can be controlled to some extent be electrical means. Motion of the charged droplets ...
متن کاملElectrospray cone-jet breakup and droplet production for electrolyte solutions
The production of charge droplets via the electrospray of an electrolyte is experimentally and theoretically found to be a Coulombic fission phenomenon that occurs when induced space charge at the microjet interface reaches a critical density as the charge separation approaches the Bjerrum length. The field surrounding the cone is dominated by the Taylor harmonic, which is responsible for induc...
متن کاملSimulation of atmospheric transport and droplet-thin film collisions in desorption electrospray ionization.
Computational fluid dynamics is used to model atmospheric transport and droplet-thin film (surface) collisions in desorption electrospray ionization; experimentally obtained droplet properties are replicated in the simulations while a "droplet pick-up" mechanism of analyte transport is confirmed.
متن کاملDetecting large biomolecules from high-salt solutions by fused-droplet electrospray ionization mass spectrometry.
A novel fused-droplet electrospray ionization (FD-ESI) source was developed to generate peptide and protein ions. The sample solution was first ultrasonically nebulized to form fine aerosols. The aerosols were then purged into a glass reaction chamber via nitrogen. Charged methanol droplets were continuously generated through electrospraying the acidic methanol solution from a capillary, which ...
متن کاملA multifunctional microfluidic droplet-array chip for analysis by electrospray ionization mass spectrometry.
This paper describes a multifunctional semi-closed droplet-array chip coupled with electrospray ionization mass spectrometry (ESI-MS) detection for multiple sample pretreatment and analysis. A novel interfacing method for coupling droplet system with ESI-MS was proposed using a sampling probe-two-dimensional (2D) droplet-array strategy. The 2D droplet-array system was composed of an 8 × 8 micro...
