Our Capabilities

Mass Spectrometry

Structural identification of volatile & semi-volatile organic species, oligomeric/polymeric components and formulations

Gas chromatography-mass spectrometry (GC-MS) for identification of volatile species
MALDI-ToF for characterisation of oligomers and polymers
Thermal desorption (TD) GC-MS for evolved volatiles and thermal degradation
Headspace GC-MS, for characterisation of volatile components
Pyrolysis GC-MS for characterisation of non-soluble polymers
Liquid chromatography-mass spectrometry ( LC-MS) for identification of semi-volatile species. See pentaerythritol example
Gel-permeation chromatography-mass spectrometry (GPC-MS), for identification of oligomeric species
Tandem mass spectrometry (MS/MS) for detailed structural information

In deformulation studies these methods provide detailed characterisation of volatile, semi-volatile, oligomeric and polymeric components. Excellent synergy with NMR and other MS techniques within MSG.
Characterisation of cross-linked or insoluble polymers for identification.
Identification of degradation products from polymer formulations.
Identification of end groups in polymers & differentiation between cyclic and linear oligomers. This information can help determineproduct quality.
Characterisation of low level volatile undesirable impurities, e.g. in monomers.
Identification of volatiles, e.g. for cause of bubbles in materials.
Provides understanding of causes of polymerisation problems from monomer impurity content or contamination of feedstocks.
Identification of additives from polymeric formulations, such as antioxidants and UV absorbers.
Identification and quantification of migratory species for regulatory work.

There is excellent synergy with NMR spectroscopy and other groups within MSG.
World leaders in end group analysis to ensure products properties and quality are met.
