Abstract: The number and size of free resin particles, which give rise to problems in the manufacture of paper, are determined so that said particles may be bound to the wood fibres by the addition of auxili- aries in order to neutralize them. Following preparation of a paper pulp suspension, the resin particles are separated therefrom, marked with a fluorescent die and isolated. The light signals emit- ted by the individual resin particles after excitation are detected to enable the number and size of the particles to be determined.
