Advanced cellulose analytics

  • Novel analysis procedures for carbonyls (CCOA method) and carboxyls (FDAM method) in pulp,
  • Profiles of oxidized groups in cellulosic materials
  • Monitoring of oxidative and aging processes (bleaching sequences, electron-beaming, light- and heat-induced yellowing)
  • Resonance-Raman studies of cellulosics
  • Detection, labelling and chemistry of hexenuronic acids (HexA) in pulps
