Electrostatic-Spray Ionization Mass Spectrometry

Hubert Girault, Natalia Gasilova, Liang Qiao, Yu Lu, Elena Tobolkina, Romain Sartor

An electrostatic-spray ionization (ESTASI) method has been used for mass spectrometry (MS) analysis of samples deposited in or on an insulating substrate. The ionization is induced by a capacitive coupling between an electrode and the sample. In practice, ...

Contribution to modeling multipactor and corona discharges in high power electromagnetic fields

Francisco Edén Sorolla Rosario

Multipactor and microwave corona breakdown are two high frequency discharges occurring within microwave components for space applications as well as within particle accelerators. The appearance of these phenomena results in the exponential growth of the el ...

Observation of ion coalescence in Orbitrap Fourier transform mass spectrometry

Yury Tsybin, Luca Fornelli

RATIONALE Similar to other mass spectrometric technologies based on ion trapping in a spatially restricted area, the performance of Orbitrap Fourier transform mass spectrometry (FTMS) is affected by the interaction between the trapped ion clouds. One of th ...

Fragmentation methods on the balance: unambiguous top–down mass spectrometric characterization of oxaliplatin–ubiquitin binding sites

Paul Joseph Dyson, Yury Tsybin, Christian Hartinger

The interaction between oxaliplatin and the model protein ubiquitin (Ub) was investigated in a top-down approach by means of high-resolution electrospray ionization mass spectrometry (ESI-MS) using diverse tandem mass spectrometric (MS/MS) techniques, incl ...

Evolution of the observed Ly alpha luminosity function from z=6.5 to z=7.7: evidence for the epoch of reionization?

Jean-Paul Richard Kneib, Frédéric Courbin, Benjamin Yvan Alexandre Clement

Aims. Ly alpha emitters (LAEs) can be detected out to very high redshifts during the epoch of reionization. The evolution of the LAE luminosity function with redshift is a direct probe of the Ly alpha transmission of the intergalactic medium (IGM), and the ...

Stark coefficients for highly excited rovibrational states of H2O

Thomas Rizzo, Oleg Boyarkine, Maxim Grechko, Oleg Aseev

Quantum beat spectroscopy is combined with triple-resonance vibrational overtone excitation to measure the Stark coefficients (SCs) of the water molecule for 28 rovibrational levels lying from 27 600 to 41 000 cm−1. These data provide a stringent test for ...

Combination of Gas-Phase Fractionation and MS3 Acquisition Modes for Relative Protein Quantification with Isobaric Tagging

Loïc Dayon, Martin Kussmann

Relative quantification of peptides and proteins with isobaric tags such as iTRAQ or TMT is commonly used in comparative quantitative proteomics based on tandem mass spectrometry (MS/MS). Nonetheless, isobaric tagging inherently suffers from the cofragment ...

State-resolved spectroscopy of high vibrational levels of water up to the dissociative continuum

Thomas Rizzo, Pavlo Maksyutenko, Maxim Grechko

We summarize here our experimental studies of the high rovibrational energy levels of water. The use of double-resonance vibrational overtone excitation followed by energy-selective photofragmentation and laser-induced fluorescence detection of OH fragment ...
