Intertek MSG Mass Spectrometry

• 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
• 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.
