A Microionizer for Portable Mass Spectrometers Using Double-Gated Isolated Vertically Aligned Carbon Nanofiber Arrays

We report a gas ionizer based on arrays of microfabricated double-gated isolated vertically aligned carbon nanofibers (VA-CNFs) for application in low-power portable mass spectrometers. Field-emitted electrons from VA-CNFs are accelerated to high energy and subsequently collide with neutral gas mole...
