Coupling Isoelectric Focusing Gel Electrophoresis to Mass Spectrometry by Electrostatic Spray Ionisation

Hubert Girault, Liang Qiao, Elena Tobolkina

Gel electrophoresis has been used for decades as a high-resolution separation technique for proteins and protein isomers, but limited in the coupling with MS because of low throughput and poor automaticity compared with LC-MS. In this work, we have develop ...

Development of a ToF setup with an ion - guide for characterization of electrospray microthrusters

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

Electrospray microthrusters are a very promising micro-propulsion system which can potentially provide very high specific impulse (Isp ~ 3000s). In this paper, we report on the development of a time-of-flight (ToF) measurement setup for characterization of ...

Dual-Channel Electrospray Microchip

Hubert Girault, Niels Erik Lion, Fang Liu, Yu Lu

A dual-channel electrospray microchip has been developed for electrospray ionization mass spectrometry (ESI-MS) where aqueous samples are mixed at the Taylor cone with an organic buffer. Due to the fast and effective mixing in the Taylor cone, the aqueous ...

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, ...

Proteolysis in microfluidic droplets: an approach to interface protein separation and peptide mass spectrometry

Hubert Girault, Liang Qiao

A versatile microreactor protocol based on microfluidic droplets has been developed for on-line protein digestion. Proteins separated by liquid chromatography are fractionated in water-in-oil droplets and digested in sequence. The microfluidic reactor acts ...

In-Spray Supercharging of Peptides and Proteins in Electrospray Ionization Mass Spectrometry

Hubert Girault, Yury Tsybin, Luca Fornelli, Yu Lu, Sasa Miladinovic, Krzysztof Marek Piech

Enhanced charging, or supercharging, of analytes in electrospray ionization mass spectrometry (ESI MS) facilitates high resolution MS by reducing an ion mass-to-charge (m/z) ratio, increasing tandem mass spectrometry (MS/MS) efficiency. ESI MS superchargin ...

Wafer-level integrated electrospray emitters for a pumpless microthruster system operating in high efficiency ion-mode

Herbert Shea, Caglar Ataman, Simon Dandavino

Microfabrication, wafer-level integration, and characterization of internally fed arrays of electrospray thrusters for spacecraft propulsion are discussed. 5 μm inner diameter, 100 μm long capillaries and 150-to-300 μm diameter annular extractor electrodes ...

Microfabrication of Capillary Electrospray Emitters and ToF Characterization of the Emitted Beam

Herbert Shea, Caglar Ataman, Simon Dandavino

Microfabrication, assembly, and characterization of internally fed arrays of electrospray emitters for spacecraft propulsion are discussed. Several different emitter geometries were fabricated, and the sprayed beams from these emitters are characterized fo ...
