GlossaryElectrospray Ionization Mass Spectrometry

analyzes molecules by converting them into charged particles

Electrospray Ionization Mass Spectrometry (ESI-MS) is a technique used to analyze the mass and structure of molecules by converting them into charged particles (ions) using an electric field. This method is particularly useful for studying large biomolecules like proteins and peptides, as it allows for the gentle ionization of these complex structures without breaking them apart.
