Nanobubbles in Electrospray Ionization Mass Spectrometry. [PDF]

Anal Chem
Nanobubbles (NBs) are very small gas-filled cavities in solvents, and when their sizes reach diameters around 200 nm, they remain in solution for extended periods of time, featuring special chemical and physical properties. Here, we investigate the application of NBs in electrospray ionization.

Neutral particle Mass Spectrometry with Nanomechanical Systems [PDF]

, 2015
Current approaches to Mass Spectrometry (MS) require ionization of the analytes of interest. For high-mass species, the resulting charge state distribution can be complex and difficult to interpret correctly.

Principles of Electrospray Ionization [PDF]

Molecular & 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.
