Electrospray Post-Ionization Mass Spectrometry of Electrosurgical Aerosols [PDF]

Journal of the American Society for Mass Spectrometry, 2011
The feasibility of electrospray (ES) ionization of aerosols generated by electrosurgical disintegration methods was investigated. Although electrosurgery itself was demonstrated to produce gaseous ions, post-ionization methods were implemented to enhance the ion yield, especially in those cases when the ion current produced by the applied ...

Transformation of neutral rhenium compounds during electrospray ionization mass spectrometry [PDF]

, 1997
Four neutral rhenium compounds were examined by electrospray ionization mass spectrometry. Acetonitrile solutions of (Ind)Re(CO)3 (Ind = indenyl) and (Cp)Re(CO)3 (Cp = cyclopentadienyl) gave rise to [Re(CO)3(CH3CN)3]+ ions.

A tutorial in small molecule identification via electrospray ionization‐mass spectrometry: The practical art of structural elucidation

Mass spectrometry reviews (Print), 2017
The identification of unknown molecules has been one of the cornerstone applications of mass spectrometry for decades. This tutorial reviews the basics of the interpretation of electrospray ionization‐based MS and MS/MS spectra in order to identify small‐

Deep Learning Approach for Dynamic Sampling for Multichannel Mass Spectrometry Imaging [PDF]

arXiv, 2022
Mass Spectrometry Imaging (MSI), using traditional rectilinear scanning, takes hours to days for high spatial resolution acquisitions. Given that most pixels within a sample's field of view are often neither relevant to underlying biological structures nor chemically informative, MSI presents as a prime candidate for integration with sparse and dynamic

Electrospray ionization tandem mass spectrometry of monoketone curcuminoids [PDF]

Rapid Communications in Mass Spectrometry, 2020
RationaleAlthough monoketone curcuminoids (MKCs) have been largely investigated due to their biological activities, data on the gas‐phase fragmentation reactions of protonated MKCs under collision‐induced dissociation (CID) conditions are still scarce.

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

Molecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Prospects in Analytical Atomic Spectrometry [PDF]

Russian Chemical Reviews, v. 75, pp. 289-302 (2006). [Translated from Uspekhi Khimii, v. 75, pp. 322-338 (2006)], 2006
Tendencies in five main branches of atomic spectrometry (absorption, emission, mass, fluorescence and ionization spectrometry) are considered. The first three techniques are the most widespread and universal, with the best sensitivity attributed to atomic mass spectrometry.

Detection and Quantification of 3,5,3′-Triiodothyronine and 3,3′,5′-Triiodothyronine by Electrospray Ionization Tandem Mass Spectrometry [PDF]

, 2005
A novel and rapid method for identifying and quantifying 3,5,3′-triiodothyronine (T3) and 3,3′,5′-triiodothyronine (rT3; reverse T3) has been introduced using electrospray ionization tandem mass spectrometry (ESI-MS/MS).
