About the Electrospray Ionization Source in Mass Spectrometry: Electrochemistry and On-chip Reactions

Hubert Girault, Joël Stéphane Rossier, Michel Prudent, Niels Erik Lion, Christophe Roussel, Bin Su, Manuel Alejandro Méndez Agudelo

The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal ions and b ...

Magnetic forces produced by rectangular permanent magnets in static microsystems

Hubert Girault, Joël Stéphane Rossier, Anne-Laure Gassner, Mélanie Abonnenc, Hong-Xu Chen

Finite element numerical simulations were carried out in 2D geometries to map the magnetic field and force distribution produced by rectangular permanent magnets as a function of their size and position with respect to a microchannel. A single magnet, two ...

Microfabricated Dual Sprayer for On-Line Mass Tagging of Phosphopeptides

Hubert Girault, Joël Stéphane Rossier, Michel Prudent, Niels Erik Lion

Phosphopeptides tagging reactions by dinuclear zinc(II) complexes (1,3-bis[bis(2-pyridylmethyl)amino]-propan- 2-olato dizinc(II)3+, called tag) were performed with a dual-channel microsprayer in electrospray ionization mass spectrometry. The reaction is fi ...

Mechanical control of fluids in micro-analytical devices

Hubert Girault, Joël Stéphane Rossier, Joël Rossier, Xiaoxia Bai

An apparatus for manipulating fluid samples comprises a micro-chip device having first and second covered channels, each channel having openings at both ends. The channels intersect to form a common intersection. Three of the openings of the channels are c ...

Thin chip microsprayer system coupled to quadrupole time-of-flight mass spectrometer for glycoconjugate analysis

Hubert Girault, Joël Stéphane Rossier, Niels Erik Lion

A thin chip polymer-based microsprayer has been coupled to a hybrid quadrupole time-of-flight mass spectrometer (QTOF MS) and introduced in carbohydrate research. The feasibility of the approach is demonstrated for mapping, sequencing and structural elucid ...
