Extractive electrospray ionization is a spray-type, ambient ionization method that uses two merged sprays, one of which is generated by electrospray. [ 49 ] Laser-based electrospray-based ambient ionization is a two-step process in which a pulsed laser is used to desorb or ablate material from a sample and the plume of material interacts with ...
This cone was described by Sir Geoffrey Ingram Taylor in 1964 before electrospray was "discovered". [1] This work followed on the work of Zeleny [2] who photographed a cone-jet of glycerine in a strong electric field and the work of several others: Wilson and Taylor (1925), [3] Nolan (1926) [4] and Macky (1931).

Electrospray is used in some air purifiers. Particulate suspended in air can be charged by aerosol electrospray, manipulated by an electric field, and collected on a grounded electrode. This approach minimizes the production of ozone which is common to other types of air purifiers.
Ambient ionization techniques are attractive for many samples for their high tolerance to complex mixtures and for fast testing. EESI has been employed for the rapid characterization of living objects, [ 10 ] native proteins , [ 11 ] and metabolic biomarkers .
Secondary electrospray ionization mechanism diagram. In the early days of SESI, two ionization mechanisms were under debate.: the droplet-vapor interaction model postulates that vapors are adsorbed in the electrospray ionization (ESI) droplets, and then reemitted as the droplet shrinks, just as regular liquid phase analytes are produced in electrospray ionization; on the other hand, the ion ...
Malcolm Dole (March 4, 1903 – November 29, 1990) was an American chemist known for the Dole Effect in which he proved that the atomic weight of oxygen in air is greater than that of oxygen in water [1] and for his work on electrospray ionization, polymer chemistry, and electrochemistry.
Probe electrospray ionization (PESI) is an electrospray-based ambient ionization technique which is coupled with mass spectrometry for sample analysis. [1] [2] Unlike traditional mass spectrometry ion sources which must be maintained in a vacuum, ambient ionization techniques permit sample ionization under ambient conditions, allowing for the high-throughput analysis of samples in their native ...
Ion beam deposition (IBD) is a process of applying materials to a target through the application of an ion beam. [1]Ion beam deposition setup with mass separator. An ion beam deposition apparatus typically consists of an ion source, ion optics, and the deposition target.
