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.

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 ...

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.

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.
