The principal factors that control properties and end-use performance of paper products are fibre characteristics, process variables, and sheet structure. Measurement of intrinsic fibre properties and their uniformity, and understanding the effects of processing are important for both pulp suppliers and papermakers.

The unique feature of confocal laser scanning microscopy (CLSM) is its ability to produce non-destructive optical sections from wood and pulp samples. With image analysis, the CLSM technique can be used to accurately determine transverse dimensions, and the fibril angle of individual fibres, thus allowing EvaluTree™ to quantify an important quality parameter: uniformity.

We offer advanced direct fibre characterization with confocal laser scanning microscopy and image analysis on:

• Cross-sectional area
• Fibre perimeter
• Wall thickness
• Fibril angle
• Early/latewood proportion and their distributions in pulps and woods
