Dilution‐Free Analysis from Picoliter Droplets by Nano‐Electrospray Ionization Mass Spectrometry

Abstract

Packaged, transferred, and delivered: A method has been developed that automatically transfers the contents of oil-encapsulated aqueous plugs to a co-flowing aqueous stream, which enables dilution-free electrospray ionization (ESI) mass spectrometric analysis for droplet-based microfluidics.
