Producing absorption mode Fourier transform ion cyclotron resonance mass spectra with non-quadratic phase correction functions

Yury Tsybin, Anton Kozhinov, Konstantin Zhurov, Konstantin Nagornov

RATIONALE: Previously described methods for producing absorption mode Fourier transform ion cyclotron resonance (FTICR) mass spectra have all relied on the phase correction function being quadratic. This assumption has been found to be invalid for some ins ...

Spectroscopic studies of kinetically trapped conformations in the gas phase: the case of triply protonated bradykinin

Thomas Rizzo, Liudmila Voronina

Understanding the relation between the gas-phase structure of biological molecules and their solution-phase structure is important when attempting to use gas-phase techniques to address biologically relevant questions. Directly after electrospray ionizatio ...

A hydrodynamically optimized nano-electrospray ionization source and vacuum interface

Klaus Kern, Mark Pauly, Stephan Rauschenbach, Gordon Rinke

The coupling of atmospheric pressure ionization (API) sources like electrospray ionization (ESI) to vacuum based applications like mass spectrometry (MS) or ion beam deposition (IBD) is done by differential pumping, starting with a capillary or pinhole inl ...

A ToF-MS with a Highly Efficient Electrostatic Ion Guide for Characterization of Ionic Liquid Electrospray Sources

Herbert Shea, Caglar Ataman, Daniel George Courtney, Simon Dandavino, Subha Chakraborty

We report on the development of a time-of-flight (ToF) mass spectrometer with a highly efficient electrostatic ion guide for enhancing detectability in ToF mass spectrometry. This 65-cm long ion guide consists of 13 cascaded stages of Einzel lens to collec ...

Chemical Modification of Graphene via Hyperthermal Molecular Reaction

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Sabine Abb, Gordon Rinke

Chemical functionalization of graphene is achieved by hyperthermal reaction with azopyridine molecular ions. The one-step, room temperature process takes place in high vacuum (10(7) mbar) using an electrospray ion beam deposition (ES-IBD) setup. For ion su ...

On-Chip Spyhole Mass Spectrometry for Droplet-Based Microfluidics

Hubert Girault, Liang Qiao, Natalia Gasilova, Qiuliyang Yu

For efficient coupling of droplet-based microfluidics with mass spectrometry (MS), a spyhole drilled on the top of a microchip is used to sample the passing droplets by electrostatic-spray ionization (ESTASI) MS. The technique involves placing an electrode ...
