A cation refers to an atom or a group of atoms that bear one or multiple positive electric charges. An anion refers to an atom or a group of atoms that bear one or multiple negative electric charges.

LC-MS/MS remains central for PFAS quantification because ESI efficiently ionizes strongly acidic, predominantly anionic PFAAs ...

Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...

Dual charge carriers in ionomer-solid contact electrification. a) Schematic illustration of charge carriers in ionomers and non-ionic polymer in contact with FEP counter material; electron, anion, and ...
