Principles of Electrospray Ionization [PDF]
Molecular & Cellular Proteomics, 2011 Electrospray ionization is today the most widely used ionization technique in chemical and biochemical analysis. Interfaced with a mass spectrometer it allows the investigation of the molecular composition of liquid samples. With electrospray a large variety of chemical substances can be ionized.

Multitrack electrospray chips [PDF]
Journal of Mass Spectrometry, 2006 AbstractMultitrack electrospray chips (MTEC) were fabricated by UV‐photoablation of polyethylene terephthalate (PET) substrates. They are composed of an array of up to six microchannels that are successively used as electrospray ionization (ESI) emitters for mass spectrometry (MS).

Electrospray Nanocoating of Microfibres [PDF]
Solid State Phenomena, 2008 The paper presents experimental results of electrospray deposition of nanopowder onto microfibers. The process is designed to form fibrous filters with an enhanced collection efficiency in the submicron range by covering the fabric with a catalytic material. Polyamide fibres were coated with Al2O3, ZnO, MgO, or TiO2 nanoparticles.

Controlling of Electrospray Deposition for Micropatterns [PDF]
Micromachines, 2018 Based on the electrohydrodynamic (EHD) theory, a novel method of near-field electrospray is proposed to fabricate micropatterns with micro/nano-scale particles. Compared with conventional electrospray technology, the deposition area can be decreased to print a regular pattern according to the moving trajectory of the substrate by shortening the ...

Printing photovoltaics by electrospray
Opto-Electronic Advances, 2020 Solution processible photovoltaics (PV) are poised to play an important role in scalable manufacturing of low-cost solar cells. Electrospray is uniquely suited for fabricating PVs due to its several desirable characteristics of an ideal manufacturing process such as compatibility with roll-to-roll production processes, tunability and uniformity of ...

On the use of hypodermic needles in electrospray [PDF]
EPJ Web of Conferences, 2013 EPJ Web of Conferences, 54, 01128-2 - 01128-5 We present an experimental analysis of electrospray where the standard feeding capillary was re placed with a hypodermic needle. Both the current intensity and the jet diameter were measured for a variety of leaky-dielectric liquids. The results obtained with a feeding capillary and a hypodermic needle

Pharmaceutical Applications of Electrospraying
Journal of Pharmaceutical Sciences, 2016 The electrohydrodynamic atomization technique, or simply called electrospraying, has been extensively studied for biomedical as well as for pharmaceutical applications over the past years. The simplicity, flexibility, and efficiency of producing particles at the microscale or nanoscale, with tailored size, shape, morphology, and microstructure, make ...

Electrospray mass spectrometry of borane salts: The electrospray needle as an electrochemical cell [PDF]
Journal of the American Society for Mass Spectrometry, 1995 Two borane salts ([(Me)4N][B3H8] and Cs[B3H8]) were examined by electrospray mass spectrometry in the positive ion mode. Acetonitrile solutions provided the most informative spectra; the salts exhibited a remarkable degree of clustering under electrospray conditions, and virtually all signals corresponded to cationic cluster ions of the general formula

Efficiency of nano-electrospray ionization [PDF]
Journal of the American Society for Mass Spectrometry, 2005 The efficiency of nano-electrospray ionization, defined as the flux of ions reaching the detector of a triple-quadrupole mass spectrometer divided by the flux of analyte ions leaving the needle, has been measured in a series of controlled experiments with dodecyltrimethyl ammonium (DDTMA) bromide, myoglobin, Glu- [1]-fibrinopeptide, and gramicidin S ...
