Ambient mass spectrometry ... and ionization of analytes present at or near the surface. Many variants of ambient MS methods have surfaced since the introduction of desorption electrospray ...

Detecting tryptophan and other metabolites can be done using various techniques. Researchers created a new UHPLC–MS/MS-based ...

It builds on an existing technology called DESI-MS (Desorption Electrospray Ionization Mass Spectrometry), a powerful tool that allows scientists to analyse complex biological samples without the need ...

With singly charged ions the mass difference is 1Da with doubly charged ½ etc. In EI-spectra one can expect mainly single charged ions, double charged ions occur with highly unsaturated compounds.

The article, “Single-Cell Mass Spectrometry Imaging of Lipids in HeLa Cells via Tapping-Mode Scanning Probe Electrospray Ionization”, was published in Communications Chemistry at DOI ...
