New Tools for Fibre Analysis
Innventia continuously works to meet the increasing demand for characterization of fibres and fines. Currently a new promising principle is being investigated. It allows for fast measurement of the volumes of suspended particles. The new technique has a potential to quickly (within minutes) give the size distribution for fibres and fines in a suspension.
The system continuously assesses partial volumes along the length of a particle. It could allow for a method to continuously monitor fibre coarseness individually along each fibre. It could have a potential for measuring fibre length and wall thickness as well. As such it would be a valuable addition to the tools and techniques used for characterizing pulp.
The true potential of the proposed system is currently being evaluated within the framework of on-going research projects. If proven successful, it could give an opportunity to develop a new powerful tool for fast measurements of the distribution of coarseness and other vital parameters for individual fibres in a fibre suspension. It would then find application in areas such as fractionation, refining and retention studies.
