Sputtering produced by vacuum electrospray droplet ions with different sizes and charges

Autor: Satoshi Ninomiya, Lee Chuin Chen, Kenzo Hiraoka

Publikováno v: Journal of Vacuum Science & Technology B. 41

We have been developing a vacuum electrospray droplet ion (V-EDI) beam technique that uses water droplet ions generated by electrospraying aqueous solutions under vacuum. The V-EDI beam is one of the massive cluster ion beams that have the potential

Automated sample preparation for electrospray ionization mass spectrometry based on CLOCK- controlled autonomous centrifugal microfluidics

Autor: Masahiro Futami, Hiroki Naito, Satoshi Ninomiya, Lee Chuin Chen, Tomohiko Iwano, Kentaro Yoshimura, Yoshiaki Ukita

We report a centrifugal microfluidic device that automatically executes sample preparation at steady-state rotation for clinical applications using mass spectrometry. The autonomous microfluidic device was designed for the control of liquid operation

Pulsed Nano-Electrospray Ionization with a High Voltage (4000 V) Pulse Applied to Solutions in the Range of 200 ns to 1 ms

Autor: Satoshi Ninomiya, Kenzo Hiraoka

Publikováno v: Journal of the American Society for Mass Spectrometry. 31:693-699

To initiate electrospray, it is necessary to accumulate excess charges on the liquid surface until the outward electrostatic pressure (PE) overwhelms the inward pressure Pγ originating from the surface tension of the liquid droplet. In this report,

Corona Discharge and Field Electron Emission in Ambient Air Using a Sharp Metal Needle: Formation and Reactivity of CO3−• and O2−•

Autor: Kenzo, Hiraoka, Stephanie, Rankin-Turner, Satoshi, Ninomiya, Haruo, Shimada, Kazumasa, Kinoshita, Shinichi, Yamabe

Publikováno v: Mass Spectrometry

CO3−• and O2−• are known to be strong oxidizing reagents in biological systems. CO3−• in particular can cause serious damage to DNA and proteins by H• abstraction reactions. However, H• abstraction of CO3−• in the gas phase has no
