Web9 de nov. de 2024 · In-source collision-induced dissociation (CID) is commonly used with single-stage high-resolution mass spectrometers to gather both a molecular formula and structural information through the collisional activation of analytes with residual background gas in the source region of the mass spectrometer. WebCID or CAD refers to the process whereby the ions kinetic energy has been increased prior to colliding with neutral molecules converting kinetic energy to internal energy that can induce fragmentation. CID is associated with ion trap activation that is performed by applying an on-resonance RF for a user-defined duration.
