Matrix-Assisted Laser Desorption Ionization Mass Spectrometry (MALDI MS)

Instrument: Autoflex Speed TOF/TOF System (Bruker)

Method for characterization of synthetic polymers and biopolymers

  • Analysis of monomer units, cyclic structures as well as start/head and end groups in polymerchains

  • Determination of molecular masses and molecular mass distributions of homo- and copolymers with narrow polydispersity (pd <  1.2)

  • Characterization of products of decomposition and by- products

  • Using of MALDI data for interpretation and discussion of reaction mechanisms

  • Coupling of MALDI with chromatographic techniques in order to characterize the molecular and chemical heterogeneities of polymers
