  • Examples of application of Raman a infrared spectroscopy:

    Material chemistry

  • study of composition and degradation of materials
  • study of microsamples in the diamond anvil cell
  • instrumentation allows the collection of infrared spectra of materials at low-concentration levels
  • carbon / carbon composites
  • corrosion products
  • structural study of nanocomposites

  • Environmental analysis

  • fly ash composition
  • investigation of soil humic substances from different environments, ion exchange properties
  • study of natural sorbents (e.g. zeolites, oxihumolites)
  • organic and anorganic matter in soils (minerals)
  • determination of polar and non-polar organic samples in natural and waste water and soils

  • Historical objects

  • analytical characterisation of pigments and binders in historical and archaeological objects
  • classication of document papers and inks

  • Food chemistry

  • analytical of edible oils - e.g. determining cis and trans isomers, oxidation
  • an infrared and raman investigation of chitin and chitosan
  • determination of chemical composition of honey, chocolate, fats, juices etc.
  • spectroscopic determination of the structure of pectins

  • Chemistry of coal and fuels

  • changes in the structure of coals of different rank, oxidation, pyrolysis etc
  • characterisation of coal degradation products - tars, pitch, phenol concentrates etc.
  • coal oxidation
  • spectroscopy study of composition and degradation of oils

  • Pharmaceutical analysis
