Electrospray Ionization Mass Spectrometric Analysis of Highly Reactive Glycosyl Halides

Molecules, 2012
Highly reactive glycosyl chlorides and bromides have been analysed by a routine mass spectrometric method using electrospray ionization and lithium salt adduct-forming agents in anhydrous acetonitrile solution, providing salient lithiated molecular ions [

Solvent-Assisted Electrospray Ionization for Direct Analysis of Various Compounds (Complex) from Low/Nonpolar Solvents and Eluents

, 2016
Electrospray ionization (ESI) is a powerful ionization technique with a wide range of applications. However, the analytes in low/nonpolar solvents cannot be analyzed directly in electrospray ionization–mass spectrometry (ESI-MS), because low/nonpolar ...

Light-Dependent Changes in the Spatial Localization of Metabolites in Solenostemon scutellarioides (Coleus Henna) Visualized by Matrix-Free Atmospheric Pressure Electrospray Laser Desorption Ionization Mass Spectrometry Imaging

Frontiers in Plant Science, 2018
The visualization of foliage color in plants provides immediate insight into some of the compounds that exist in the leaf. However, many non-colored compounds are also present; their cellular distributions are not readily identifiable optically.

Ionization Process and Electrospray.

Journal of the Mass Spectrometry Society of Japan, 1996
Scientist observed natural phenomena and found the existence of ions more than 100 years ago. When the historical background of electrospray was surveyed from the view point of the ionization technique, the origin started by the awareness of the charged drops in nature. Our earth is positively charged and abounds in the positive ion.

Characterisation of electrospray properties in high vacuum with a view to application in colloid thruster technology [PDF]

, 2005
PhDThe operational environment of colloid thrusters is high vacuum (10-3 _ 10-6 mbar) however, much of the experimental data collected to date to identify parameter relationships in cone jet mode electrosprays (ES), such as current-volumetric flow ...

Solution structure of a seven coordinated manganese(II) complex via electrospray ionization mass spectrometry

, 2010
The mononuclear complex [Mn(tptz)(CH3COO)(OH2)2]NO3 (1) was investigated by electrospray ionization mass spectrometry in aqueous solution at pH 4.5. Electrospray ionization mass spectrometry shows that mononuclear and dinuclear manganese cationic species

Pulsed probe electrospray and nano-electrospray: the temporal profiles of ion formation from the Taylor cone

, 2017
The temporal profiles of ion signals were measured for probe electrospray ionization (PESI) and nano-electrospray ionization (nESI) by changing the pulse width of the high voltage applied to the emitters.
