Electrospray Ionization Ion Mobility Mass Spectrometry

Critical Reviews in Analytical Chemistry, 2021
Electrospray ionization ion mobility mass spectrometry (ESI-IMS-MS) is a rapidly progressing analytical technique for the examination of complex compounds in the gas phase. ESI-IMS-MS separates isomers, provides structural information, and quantitatively identifies peptides, lipids, carbohydrates, polymers, and metabolites in biological samples.

Arc-Induced Electrospray Ionization Mass Spectrometry

Analytical Chemistry, 2023
Arc-induced electrospray ionization mass spectrometry (AESI-MS) was developed during which alternating current electrospray is simply achieved through the arc plasma. The AESI source exploits the arc's temperature and charge properties to generate aerosols consisting of charged microdroplets.

Electrospray ionization mass spectrometry of ginsenosides

Journal of Mass Spectrometry, 2002
AbstractGinsenosides Rb1, Rb2, Rc, Rd, Re, Rf, Rg1, Rg2 and F11 were studied systematically by electrospray ionization mass spectrometry in positive‐ and negative‐ion modes with a mobile‐phase additive, ammonium acetate. In general, ion sensitivities for the ginsenosides were greater in the negative‐ion mode, but more structural information on the ...

Electrospray Ionization Mass Spectrometry of Oligonucleotides

Current Protocols in Nucleic Acid Chemistry, 2008
AbstractBecause of the high molecular weights and thermal lability of biomolecules such as nucleic acids and protein, they can be difficult to analyze by mass spectrometry. Such analyses require a “soft” ionization method that is capable of generating intact molecular ions.

Electrospray ionization mass spectrometry of metalloporphyrins

Journal of Mass Spectrometry, 1998
The magnesium, nickel, copper, zinc and vanadium metalloporphyrins from octaethylporphyrin, etioporphyrin I and tetraphenylporphyrin were characterized using electrospray ionization mass spectrometry (ESI-MS). The ion abundance of each of the porphyrins present in binary mixtures was monitored as a function of the porphyrin concentration and is ...

Electrode‐assisted desorption electrospray ionization mass spectrometry

Journal of Mass Spectrometry, 2010
AbstractA new ion source has been developed for rapid, noncontact analysis of materials at ambient conditions. The method provides desorption of analytes under ambient conditions directly from different surfaces with little or no sample preparation. The new method, termed electrode‐assisted desorption electrospray ionization (EADESI), is on the basis ...

Electrospray ionization mass spectrometry

2001
Abstract Characterization of protein-ligand interactions involves the determination of stoichiometry, affinity, and conformational changes associated with such interactions. Mass spectrometry is rapidly emerging as an important and powerful new tool in this area to complement the wealth of other techniques described in these volumes. The

Synchronized Desorption Electrospray Ionization Mass Spectrometry Imaging

Analytical Chemistry, 2015
Desorption electrospray ionization (DESI) has emerged as a powerful technique for mass spectral analysis and imaging under ambient conditions. Synchronization of DESI (sDESI) with the ion injection period (IT)of low-duty cycle mass spectrometers has been previously shown to improve sensitivity and reduce the amount of sample depleted during the ...
