Electrospray Ionization Mass Spectrometry: A Powerful Platform for Noble-Metal Nanocluster Analysis.
Angewandte Chemie, 2019Electrospray ionization mass spectrometry (ESI-MS) is an analytical technique that measures the mass of a sample through "soft" ionization. Recent years have witnessed a rapid growth of its application in noble-metal nanocluster (NC) analysis.

Electrospray mass spectrometry of
Journal of the American Society for Mass Spectrometry, 2000There has been a substantial growth in the application of mass spectrometry (MS) methods for the analysis of inorganic materials, due to the inherent sensitivity of mass spectrometry ionization to the specific composition and structure of the analyzed materials.

Electrospray tandem mass spectrometry of lexitropsins
Rapid Communications in Mass Spectrometry, 2001AbstractSeveral compounds, representative of the class of lexitropsins, were analyzed by electrospray tandem mass spectrometry. The study of the fragmentations of the protonated molecular species ([M + H]+) and of selected fragment ions allowed proposals for the main fragmentation pathways of compounds of this type.

Electrospray ionization mass spectrometry of ginsenosides
Journal of Mass Spectrometry, 2002AbstractGinsenosides 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 tandem mass spectrometry of polyoxoanions
Journal of the Chemical Society, Chemical Communications, 1995A number of polyoxomolybdates and polyoxotungstates are studied by means of electrospray tandem mass spertrometry; in each case, the mass spectrum of a solution of the polyoxoanion shows the polyoxoanion as the base peak with a minimal degree of fragmentation.

[21] Electrospray ionization mass spectrometry
1996Publisher Summary An electrospray ionization source operating at atmospheric pressure was first interfaced to a mass spectrometer in Fenn's laboratory at Yale University (New Haven, CT), with inspiration taken from earlier ion-stopping potential studies, using electrospray ionization conducted by Mack et al .

[22] Electrospray ionization mass spectrometry
1990Publisher Summary This chapter discusses electrospray ionization mass spectrometry. Electrospray ionization (ESI) occurs during the electrostatic nebulization of a solution of charged analyte ions by a large electrostatic field gradient (approximately 3 kV/cm). Highly charged droplets are formed in a dry bath gas, at near atmospheric pressure.

Electrospray Ionization Mass Spectrometry of Oligonucleotides
Current Protocols in Nucleic Acid Chemistry, 2008AbstractBecause 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.

Microdevices for Electrospray Mass Spectrometry
1998Two designs of microdevices for microanalysis by mass spectrometry have been developed. In both cases the electrospray is used for sample ionization and transfer of the analytes from the microdevice into the mass spectrometer. The first design incorporates a capillary electrophoresis separation channel and a micromachined pneumatic nebulizer for ...

Charge Reduction Electrospray Mass Spectrometry
Analytical Chemistry, 1999A new mass spectrometric technique, charge reduction electrospray mass spectrometry (CREMS), allowing the analysis of complex mixtures of biological molecules is described. The charge state of ions produced by electrospray ionization may be reduced in a controlled manner to yield predominantly singly charged ions through reactions with bipolar (i.e ...
