Dynamics of field-induced droplet ionization: time-resolved studies of distortion, jetting, and progeny formation from charged and neutral methanol droplets exposed to strong electric fields

Article Abstract:

The temporal evolution of droplet shapes leading to FIDI events is characterized as a function of electric field strength and droplet net charge following exposure of the droplet to a rapidly switched electric field. It is found that increasing the electric field decreases the time to form jets from both neutral and charged droplets, and the combination of net charge and higher-then-critical electric fields has a compound effect in accelerating progeny formation.

Development of cation/anion "interaction" scales for ionic liquids through ESI-MS measurements

Article Abstract:

Electrospray ionization mass spectrometry (ESI-MS) applied to ionic liquids is used to analyze the relative strength of anion-cation interaction inside the ionic liquids. The low-energy collision dissociation of loosely bonded homologous and mixed complexes has provided some vital information about the magnitude of these interactions.

Field-induced droplet ionization mass spectrometry

Article Abstract:

A method for generating desolvated ions in the gas phase on neutral droplet instability in strong electric fields is reported. The variations may involve the analysis of a single droplet, repeated sampling of an individual droplet, or the use of pulsed electric fields to analyze specifically selected droplets.
