Investigation of In‐Trap High‐Energy Collision Dissociation Methodology and Dissociation Conditions Using Dual‐Pressure Linear Ion Trap Mass Spectrometry

Validation experiments using veterinary drug residues fenoterol and ractopamine demonstrated the method's universality by comparing its dissociation results with those from conventional ion trap collision-induced dissociation (CID) and triple quadrupole method. The findings confirm that this strategy can be extended to other ion trap mass spectrometry platforms, offering broader applicability.
