Matrix‐assisted laser desorption/ionization combined with collision‐induced dissociation (CID) has been applied to the structural determination of synthetic polymers. Post‐source decay/CID experiments on a time‐of‐flight (TOF) instrument have been compared with CID data from a hybrid sector‐TOF mass spectrometer. Fragment‐ation spectra of polymers, with molecular weights of up to 4500 Da, have been shown to aid structural and end‐group determination. The polymers studied were poly(methyl methacrylate), poly(ethylene glycol) and poly(ethylene terephthalate).
