Electrospray mass spectroscopy of macromolecule degradation in the electrospray

Journal of Polymer Science: Polymer Physics Edition, 1975
AbstractAs previously shown, by electrospraying dilute polystyrene (PS) solutions gas phase macroions can be produced. Degradation of the PS in the electrospray was tested by collecting the electrosprayed PS and measuring its number‐average molecular weight osmotically.

Electrospray Ionization Mass Spectrometry: A Powerful Platform for Noble-Metal Nanocluster Analysis.

Angewandte Chemie, 2019
Electrospray ionization mass spectrometry (ESI-MS) is an analytical technique that measures the mass of a sample through "soft" ionization. Recent years have witnessed a rapid growth of its application in noble-metal nanocluster (NC) analysis.

The Background to Electrospray

2016
This article traces the development of electrospray back to its earliest beginnings. Many readers may be surprised to learn that descriptions of the electrostatic attraction of liquids to surfaces appear in the scientific literature as early as the year 1600, and that true electrospray experiments are documented to have been performed in the eighteenth

Astable regime in electrosprays

Physical Review E, 2007
Astable regimes are common in nonlinear systems ranging from electrooptic devices to cardiac rhythms under environmental stress. Electrosprays exhibit three main axial regimes (dripping, pulsating, and cone-jet). It is generally accepted that the transition between the pulsating and cone-jet regimes is sudden, accompanied by an abruptly enhanced spray ...

Functional electrospray emitters

The Analyst, 2009
Electrospray ionisation (ESI) is a soft technique used in mass spectrometry (MS) analysis able to introduce a wide variety of analytes in the gas phase. Briefly, it consists in the application of a high-voltage to a solution to spray it through a small orifice.

Ionic liquid electrospray behavior in a hybrid emitter electrospray thruster

International Journal of Heat and Mass Transfer, 2021
Abstract Electrospray thrusters are most suitable for micro-nano satellites in advantage of small size, low power consumption and high specific impulse. However, conventional electrospray thrusters with capillary emitters operate at single mode with limited range of thrust.

On the mechanism of electrospraying

Nuclear Instruments and Methods, 1970
Abstract A study was made to determine the parameters governing the formation and stability of the spray for a number of polar liquids. The dielectric constant and the surface tension were found to be dominant. A theoretical explanation is suggested.

Practical implications of some recent studies in electrospray ionization fundamentals.

Mass spectrometry reviews (Print), 2001
In accomplishing successful electrospray ionization analyses, it is imperative to have an understanding of the effects of variables such as analyte structure, instrumental parameters, and solution composition.

Electrospray cooling for microelectronics

International Journal of Heat and Mass Transfer, 2011
The challenge of effectively removing high heat flux from microelectronic chips may hinder future advancements in the semiconductor industry. Spray cooling is a promising solution to dissipate high heat flux, but traditional sprays suffer from low cooling efficiency partly because of droplet rebound.

Electrospray, technique and applications

Journal de Chimie Physique, 1993
Electrospray makes use of ions present in electrically charged droplets in an aerosol. The generation of an aerosol by electrospray has already been published by Zeleny in 1917. The feasibility of electrospray as an ionization technique was demonstrated by Fenn and coworkers, and by a group of Russian scientists in Leningrad (St.
