Principles of Electrospray Ionization [PDF]

open access: yesMolecular & Cellular Proteomics, 2011
Electrospray ionization is today the most widely used ionization technique in chemical and biochemical analysis. Interfaced with a mass spectrometer it allows the investigation of the molecular composition of liquid samples. With electrospray a large variety of chemical substances can be ionized.

Conducting and Characterizing Femto Flow Electrospray Ionization [PDF]

open access: yes, 2021
Femto flow electrospray ionization (ESI) ranging from 240 fL/min to low pico flow (< 10 pL/min) was conducted and measured using submicron emitter tip and relay ESI configuration. Signature analyte ion intensities and profiles were obtained.
