Abstract

A novel method for the characterization of polymers by laser desorption/ionization on the layer of graphene nanoparticles coupled with time-of-flight mass spectrometry was demonstrated. Various polymers including polypropylene glycol, polystyrene and polymethyl methacrylate with average molecular weights from 425 to 3500 Da were analyzed.
