Confocal Raman spectroscopy -: Applications on wood, pulp, and cellulose fibres

The manifold possibilities using dispersive Raman spectroscopy along the production chain from wood to cellulose fibre are presented here: The distribution of the lignin, cellulose, and added resins in the wood cell; additives inside regenerated cellulose fibres; their accessibility and reactivity. On-line measurements during the phase transition of magnesium sulphite hexahydrate into -trihydrate are performed in a stirring vessel.
