Classification of electrospray axial regimes as revealed by spray current measurements
A coherent classification of electrospray axial regimes is provided based on non-linear fluid dynamics as revealed by spray current measurements and fast time-lapse imaging of the electrified meniscus. The classification includes two periodic (dripping, pulsating), two transient/chaotic (burst, astable), and two stationary (cone-jet, jetting) regimes. The dripping faucet phase diagram is described as a particular case of a more complex electrospray phase diagram. Spray current measurements and electrospray characteristic curves are presented as essential for the diagnosis of the electrospray operation and the transition between its various regimes. Reaching a consensus on regime nomenclature and a standardized approach to designate transitions between electrospray regimes is suggested. Finally, the effect of the electrospray operating regime on the mass spectrometer signal is briefly summarized.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
